Many countries around the world have long used the SI metric system. In it, the main unit of measurement, for example, length is the meter, time is usually measured in seconds, weight - in grams. And depending on the situation, it is either a liter or a cubic meter.

However, things are not at all like this in countries that have not adopted So, in some countries they use quantities. These countries directly include the UK, USA, Cuba and Argentina. In addition, there are a number of states that use such a system of measures only partially.

In the five countries listed, the gallon is used as a unit of volume. However, the main disadvantage of all non-unified measurement measures is their absolute inaccuracy and the presence of a number of discrepancies. For this reason, when answering the question of how many liters are in one gallon, it is necessary to first clarify which one. Since such measures in the USA, Britain and other countries are very different from each other.

The most interesting fact is that even in one country several types of this measure are used. In the USA, for example, a gallon equal to 3.45 liters is used to measure the volume of honey, 4.4 liters are used to measure bulk solids, and 3.8 liters for wine and oil. In addition, there is such a thing as a “proof gallon,” which serves as a standard for all other units of measurement. equal to 1.89 liters.

How many liters are in a UK gallon?

The situation is similar in Britain. So, there is a type of gallon called "imperial". However, its second name is “ordinary”, and it is equal to 4.55 liters. It can be used everywhere and for any substance. In addition, the gallon used as a measure for bulk materials is equal to the American one - 4.4 liters. And also the available proof gallon is 2.6 liters. It is used to measure the volume of alcohol. The old gallon, used back in the days of kings and royal dynasties, is still in use. Now, however, it only measures wine and other liquids.

Why know how many liters are in a gallon?

Probably more than once, while listening to the news or reading them on the Internet, you have come across the phrase that it costs so much. And, probably, at least sometimes you have wondered what a barrel actually is. It is a measure of volume derived from the US gallon. More precisely, a barrel is equal to 42 US gallons or 159 liters. In addition to it, in the English system of units of measurement there are also such measures as quantum, pint, jill and others, which are also derived from the gallon. By the way, it is very noteworthy that the British, Americans and other users of this system prefer to measure the amount of milk, tea or alcohol they drink, not in bottles, glasses or glasses, but in pints.

And, in the end, no one excludes the fact that you will travel through these countries. And then knowing how many liters are in a gallon, as well as in all its derivatives, can become very useful and even necessary. Good luck to you!

Gallon - definition

Gallon (eng. gallon, gal) is a unit used to measure the volume of liquid substances and granular bodies in a number of English-speaking countries, an indicator used in assessing the efficiency of vehicles (miles traveled per gallon of fuel consumed), in sociological research and comparing the standard of living and consumption of different countries (cost of a gallon of fuel and etc.).

Gallon is unit of volume (capacity, capacity) in the English system of measures, used in England, the USA and a number of other countries.

Gallon is an indicator that allows you to evaluate the efficiency of fuel use by vehicles.

Gallon is an indicator that allows for sociological comparisons, including those related to the standard of living of the population of different countries.

Using the gallon unit

Term gallon comes from English gallon, further from Norman galon, (compare Old French jalon); from Latin galona"measure of liquid", medieval Latin gallo, gallona- “a kind of round box”, possibly from Gaulish galla"vessel".

Gallon is a measure of volume equal to 3.79 to 4.55 liters, depending on the country of use. Typically used for liquids, in rare cases for solids. Traditionally used in countries where the English system of measures was used - Great Britain, the USA and a number of others.

The unit of measurement "gallon" is closely related to the English system of units of weight and volume.

UK gallon

In Britain, the gallon was used as a unit of measurement (volume) for bulk solids and liquid products.

Measures for bulk products in Britain

Standard measures for bulk solids were introduced to Britain by the Romans.

Much later, around 871, King Alfred the Great chose the city of Winchester in southeastern England as the capital of his kingdom of Wessex.

The golden age of the Anglo-Saxon kingdoms was probably during the reign of Alfred's great-grandson, Edgar the Peaceable (reigned 959-976), possibly the first king of England. One of the problems facing Edgar was the “standardization” of weights and measures (“And let the same weights and measures be when such is used in London and Winchester.” The Laws of the Kings of England from Edmund to Henry I. Cambridge: Cambridge University Press, 1925).

This law comes into force in the third year of Edgar's reign. Winchester was then the center for the creation of standard measures. And the first was the standard measures for grains. The British would say "corn measures". In British English, "corn" means grain, including wheat, barley, etc. (Samples of corn were brought to Europe after Columbus’s second voyage: “I saw grains called maize”). In the United States, "corn" specifically means corn.

Early standards

The first measured copies of standards for various counties and cities appeared in the reign of Richard I, in 1197. Presumably the early volume standards (bushel) were made of wood and have not survived to this day. The earliest surviving bushel is a bronze vessel (made in 1497, reign of Henry VII) with a volume of 2144.81 cubic inches, another was made by order of Elizabeth I (1601) and has a volume of 2148.28 cubic inches.

Since at least the 13th century, a bushel has contained 8 gallons, and each gallon is the volume occupied by 8 pounds of wheat.

“With the consent of the whole kingdom of England regarding the measures, our lord the king ordered this: namely, that an English penny, round and without trimming, weighs as 32 grains of wheat from the middle of an ear. And 20 pennies make an ounce, and 12 ounces make a pound, which contains 20 shillings. And 8 pounds of wheat makes a gallon of wine. And 8 gallons of wheat make a London bushel, which is the eighth of a quarter." MS. Cotton, Cleo. A. XVI, f. 6. 15th century

This idea of ​​defining a unit of measurement as the volume of a given weight of a particular grain has a tradition of thousands of years, but in many ways wheat is not an ideal object for these purposes. As any farmer knows, the weight of a gallon of wheat varies depending on the moisture content. The weight even depends on the height from which the wheat is poured into the container. But wheat had an overwhelming advantage as a commodity that everyone desperately cared about.

In fact, regardless of what the law says, Henry VII's bronze standard contains not 8, but 9 gallons - 72 troy pounds of wheat (the name comes from Troyes, a city in France that was the site of large annual fairs in the Middle Ages, which attracted traders from most of Europe). The standard was made to reflect the practice in the market, where wheat was sold in crowded measures ("capped"). One of Henry VII's bushels would contain the same amount of wheat as 8 capped gallons.

To ensure uniformity, the term "Winchester Measure" appears in the Acts of Parliament in the 17th century. In 1696, in the presence of members of Parliament, Thomas Everard, the official Excise Gauger and his assistants measured the volume of Henry VII's standard exchequer bushel. They got a value of 2145.6 cubic inches. To facilitate the production of new measures, its dimensions were rounded to a cylinder 18 ½ inches in diameter and 8 inches in height. According to Everard himself, a cylindrical vessel of these dimensions would contain 2150.42 cubic inches, which exceeds the Bushel standard content by 4.82 cubic inches. This bushel was officially named: "a bushel of Winchester, according to the standard of His Majesty's Treasury."

Great Britain abolished the "Winchester bushel" only in 1824, in the act of establishing an imperial measure. In Australia, Queen Victoria abolished the Winchester bushel in 1890. In New Zealand, it was abolished in 1868. At the same time, the "simplified" bushel crossed the Atlantic and became the basis of the "dry" bushel in the United States.

Measures for liquid products in Britain

Officially, the term “wine gallon” appeared in 1706. during the reign of Queen Anne, and is sometimes called "Queen Anne's wine gallon." However, measures for wine originated in England much earlier.

The wine gallon appears to have originated as a unit used by merchants in the early medieval English trade in imported wine from France, possibly via the Flemish city of Bruges. It is therefore not surprising that the standard weight was taken to be the Parisian 8 Livre, which occupies a volume of about 224 cubic inches. Livre was divided into 15 ounces, each weighing about 30.6 grams.

In 1641 Reynolds, Trustee of the Tower created the elegant half gallon (Pottle). According to measurements taken in 1994, twice the volume of this Pottle would make a wine gallon equal to 233.06 cubic inches. It is likely that the emergence of the new wine gallon with a capacity of 231 cubic inches is due to the simplification of the construction of the measure: a cylinder 6 inches high and 7 inches in diameter has a volume of 231 cubic inches, which is not significantly different from 233.

For decades, Excisemen collected duties on wine imports using 231-cubic-inch gallons. Then in 1688 someone noted that a gallon of 224 cubic inches was a “true wine gallon.” But, looking into the files, the excisemen discovered that the Treasury had a standard only for a gallon of 272 cubic inches.

Switching to a larger gallon would have caused a large drop in the king's income (since the tax was per gallon), so the commissioners refrained from revising the standards, and in 1706 the government corrected the matter and legalized the wine gallon with a volume of 231 cubic inches.

Finally, in 1824, the British Parliament replaced all versions of the gallon with one imperial gallon, defined as 10 pounds of distilled water at 62 °F (16.67 °C), which is 277.42 cubic inches. But by this time the wine gallon had already “left” for America.

Currently, 1 gallon is equal to 4.54609 cubic meters. dm.

US Gallon

In the United States of America, the only legal gallon is a unit of liquid volume - 231 cubic inches = 3785.411784 cubic centimeters. However, this is not the only gallon that has been used in the United States previously, for example, in the late 19th century, some states used the 282-cubic-inch "milk gallon", and the "dry gallon" is still widely used today.

New York State used a liquid gallon, defined by local law as the volume occupied by 8.3389 pounds of avoirdupois water at 62 degrees Fahrenheit with a barometric pressure of 30 inches, corresponding to a volume of 221.184 cubic inches. This indicator was abolished by the act of April 11, 1852.

The US gallon is equivalent to the English wine gallon. Thus, in the US for liquids, 1 gallon = 3.78541 cubic meters. dm.

The fractional units of a gallon are a pint, equal to 1/8 of a gallon, and a fluid ounce, equal to 1/128.

In the USA there is a special measure of volume - the fluid ounce, and a measure of weight - the ounce. There is a direct relationship between these units: one fluid ounce of water contains 1 ounce of weight.

In addition, the USA has additionally introduced:

Barrel of oil (Oil barrel), (bbl - world designation, br - Russian abbreviation): 1 barrel of oil = 158.988 l = 42 US gallons = 34.9723 imperial gallons (imp gal) = 0.1589873 m3;

Liquid barrel, which is 119 liters (31.5 US gallons, 26 imp gal);

The standard beer barrel (introduced due to tax restrictions) is 117 L (31 US gallons, 26 imp gal);

The total US federal barrel is 117.348 liters (25.8129 imp gal, 31 US gallons);

The total US federal proof spirits barrel is 151.416 liters (40 US gallons, 33.3069 imp gal);

A standard liquid barrel, which is 42 US gallons, i.e.: 1 US barrel = 42 US gallons = 159 liters = 1/2 hogshead;

A US dry barrel is 7.056 cubic inches = 115.6 L (approx. 3.28 bushel).

Back in 1790, US Secretary of State Thomas Jefferson addressed Congress with a proposal to switch to the decimal system of weights and measures: “... in order to bring the arithmetic of calculation to everyone who is able to multiply and divide ordinary numbers.” But so far this has not been possible.

In the UK, back in 1965, a decision was made to switch to the metric system; the English system of units of measurement was officially phased out at midnight on December 31, 1999. However, in 2007, the EU allowed the UK to use pounds and pints because... Britain's population is still not ready for the transition.

There are only three official adherents of the “English system” left in the world: the USA, Burma and Liberia. It should be noted that the United States actually adopted the “Old English system of measures.” In 1988, Congress amended the Metric Conversion Act, according to which the metric system became “the preferred system of weights and measures of the United States for the needs of trade and commerce,” but the average American simply does not see much sense for himself in the metric system.

English system of units of measurement of weight and volume

In the English system, three categories of units are used to measure weight characteristics: measures of mass (avoirdupois),troy (for precious metals and stones) And apothecaries weight measures. Some of these measures in a number of countries differ somewhat in size, so below are mainly rounded metric equivalents of English measures, convenient for practical calculations.

Gradually, the English system was replaced by the metric system of measures. To indicate the system of units of the latter, the adjective metric is usually used, for example, “metric ton”.

Units of mass measurement avoirdupois

The values ​​of units of mass in Great Britain have changed several times over the past centuries. Below are the values ​​at the beginning of the 20th century.

The use of units of measurement: ton, quintal, quarter, stone, drachm and grain has been abolished in the UK since 1985 (Weights and Measures Act, 1985).

Options for translating units of mass avoirdupois into Russian and English abbreviations are given in the table.

In the USA large units of mass have a different numerical value.

Commonly used unit ton is equal to 900 kg, or 2000 pounds, sometimes the expression is used for it “net ton” (net ton).

When designating the weight of coal (in Pennsylvania), iron and steel in physical terms, when assessing customs duties, it is used long ton: 1 ton = 1016.047 kg, or 2240 pounds.

Unit hundredweight (hundredweight) contains 100 pounds, used from the early 18th century to the early 20th century, defined in many state laws. Nowadays it is extremely rarely used.

The quarter unit of measurement has two options: short quarter= 1/4 ton or 500 pounds, and long quarter= 1/4 long ton or 560 lbs.

Troy units of weight

In the UK and US, troy units of weight are used to estimate the weight of precious stones and metals.

Currently, only the troy ounce is officially used in the UK.

Options for translating troy weight units into Russian and English abbreviations are given in the table.

In the USA, troy weights are used(troy ounce, pennyweight, grain) are widely used.

For example, in the “Uniform Regulation for the Method of Sale of Commodities, 2013”, it is stated

“The unit of measurement and method of sale of precious metals, if the price is based in part or wholly on a determination of weight, shall be either troy weights or SI units. When a measurement or sales method is expressed in SI mass units, conversion tables to troy values ​​should be prominently displayed to facilitate price comparisons. The conversion table must also contain a table of troy weights, indicating grains, pennyweights and troy ounces.”

The weight of bullets is also indicated in grains.

The troy ounce is one of the main world units of measurement in the mining of precious metals, in the precious metals market, and in jewelry.

Weight measurement units in pharmacies

Also widely used in the English-speaking world "apothecary" weights.

Options for translating pharmaceutical weight units into Russian and English abbreviations are given in the table.

Special volume measures

In shipbuilding, when describing cargo capacity, units of volume (not weight) are used - a registered ton equal to 100 cubic feet = 2.83 cubic meters.

During transportation, volumetric measures are used:

A British shipping ton is equal to 42 cubic feet;

In the USA, a shipping ton is equal to 40 cubic feet, another name is a freight ton.

Some non-systemic measures for liquid products

Non-systemic units of liquid volume are used by bartenders when preparing cocktails.

Previously, in Russia there were a number of units for measuring liquid volumes.

Currently, the unit of measurement for everything: volume, work (plowing a garden), etc. is

Gallon as a Metric in Evaluating Efficiency

The gallon, as a standard indicator, is often used when assessing the efficiency of transport systems and means, when comparing the standard of living and consumption of different countries.

Rating of countries by cost of a gallon of gasoline

But the nominal price at the gas station itself poorly reflects the real cost of fuel for motorists. After all, a high price may not hit the wallet of a resident of a rich country as much as a formally low price does for ordinary citizens in a country with a poor population. Therefore, in addition to the formal rating, where 55 countries are ranked by the cost of a gallon of gasoline, Bloomberg compiled a rating of the “painfulness” of gasoline prices. It is calculated by the percentage of the average daily wage in the country that must be spent on purchasing one gallon of fuel.

The most expensive gasoline in Norway is $9.69 per gallon. The situation is unusual, notes Bloomberg: Norway is the only large oil-producing country with expensive gasoline. This is explained by the fact that it does not subsidize prices at gas stations, but uses petrodollars to pay for services - for example, providing free higher education and modernizing infrastructure. Norwegians, whose average daily income is $270, pay just 3.6% of it per gallon (48th place in the ranking of painful gasoline prices).

Residents of crisis-stricken Greece (5th place with $9.23) have it much harder, paying 12% of their $75 income for a gallon of gasoline (23rd position in the pain ranking). Gasoline prices in Greece are higher than the EU average.

Russia shares with Italy 29th place in the ranking of painful gasoline prices, although its nominal price is almost three times lower - only $3.71 (46th place in terms of price level). However, with an average daily income of $41, Russians have to pay 9.1% per gallon. As a result, the country, being at the bottom of the list in terms of the nominal cost of gasoline, falls almost into the very middle of the pain rating; According to this indicator, we are at the average level in the world.

The situation is diametrically opposite in the oil-rich Gulf countries. They occupy last places in both ratings - both in price and in the share of earnings that goes to pay for gasoline. Thus, Saudi Arabia, which recently overtook Russia and became the world's largest in terms of oil production, is in 54th place in terms of price ($0.61) and in 52nd place in terms of pain: a resident of the country, on average, spends per gallon gasoline 1.1% of his daily income of $55.

Alaska Airlines has reduced fuel consumption by 30% since 2004 and uses only 0.0138 gallons of fuel per passenger mile (RPM). The company currently ranks first in fuel efficiency among all major US carriers.

Efficiency of rail transport

Until now, railroad transport in the United States has primarily relied on locomotives.

Therefore, it is important to assess the efficiency of use of liquid fuel during transportation. The table provides data on passenger miles (PM = Passenger-miles, volume and distance of transportation) per unit of fuel consumed (gal = gallon of diesel fuel).

The table shows that fuel efficiency in US rail transport is not improving.

Efficiency of US passenger cars

The energy crisis has led to the introduction of more and more fuel-efficient passenger cars, mainly from Japanese brands, into the US markets.

To assess the efficiency of vehicles, the MPG indicator is used - the number of miles a car will travel using 1 gallon of fuel.

As can be seen from the figure, in the Trucks class, cars from American companies are half as efficient as those from Japanese companies.

But real Americans love big cars. Dodge Ram Prospector, 1984. A very popular brand in the USA. A huge, powerful machine. There is always a metal ram on the hood. Of course it drives like a tank. But 8 mpg is terrible. The owner spends about $100 to fill up this monster.

In the section on the question how many liters are in 1 gallon asked by the author ***natali*** the best answer is 4.5892186345 liters

Answer from Igor Onishchenko[master]
4.54 liters

Answer from Get out[master]
Gallon is a measure of volume used in countries where a system of weights and measures other than the metric system has historically developed. Typically used for liquids, in rare cases - for solids.
A gallon was originally defined as the volume of 8 pounds of wheat. Later, other varieties were introduced for other products and, accordingly, new varieties of pints appeared. America adopted the British wine gallon, defined in 1707 as 231 cubic inches, as the primary measure of liquid volume. This is where the American liquid pint was developed. The British corn gallon (268.8 cubic inches) was also adopted as a measure of the volume of bulk solids. This is where the American dry pint comes from. In 1824, the British Parliament replaced all versions of the gallon with one imperial gallon, defined as 10 pounds of distilled water at 62 °F (277.42 cubic inches).
A pint is a derivative of a gallon - one eighth of it.
In the US, the standard liquid barrel is 42 US gallons i.e. 1 US barrel = 42 US gallons = 159 liters = 1/2 hogshead. However, when measuring the volume of beer (due to tax restrictions) in the USA, the so-called standard beer barrel is used, which is equal to 31 US gallons (117.3 liters).

Answer from hundredrose[guru]
1 US gallon = 3.78541178 liters
In the UK, 1 gallon = 4.54609 liters.
It is impossible to answer this question unequivocally, since a gallon is a measure of volume that is part of a non-metric measurement system and in different countries has its own value in terms of liters.

The United States of America is a country of cars. That is why talking about gasoline in this country is very important. In the article we will consider such aspects as fuel quality, brands and, of course, find out how much gasoline costs.

Overall fuel quality

As experts often note, gasoline in the United States is of very high quality: if a driver fills up with 91 or 93, he will get the quality he paid for. In some countries (unfortunately, Russia is one of them), fraud is widespread: diluting gasoline, i.e. adding substances that harm the engine. And in this case, the guarantee that the car is actually filled with premium fuel comes to naught, since the manufacturer’s assurance alone is not enough.

Trade marks

Now about the brands represented on the United States market.

Shell is a trademark of the large British-Dutch company Royal Dutch Shell. This brand of gasoline is one of the best-selling gasoline in the United States.

Chevron is a brand of the oldest American energy company, Chevron Corporation. Prices are about a quarter higher than Shell.

Mobil 1 is a brand that is somewhat behind the above in popularity.

Interesting video. Review of an American gas station.

The cost of gasoline in America

The price of fuel in the United States is indicated in gallons (there are 3.8 liters in one gallon). Somewhere in the statistics below we will find liters, somewhere - gallons, but for convenience we will still indicate most indicators in liters.

The average price of a liter of gasoline worldwide is $1.08. At the same time, the United States is among the countries with the lowest cost of gasoline: the price per liter is $0.72.

It is interesting that the leaders here are the oil and gas powers: Venezuela, Saudi Arabia, Qatar, etc. America, without having massive oil reserves, remains in the lead, although slightly behind Russia. In addition, fuel is several times cheaper than in European countries. For example, in , than in the USA almost 2 times.

The price of gasoline varies greatly by state. In addition, many people note that even in the same city the cost may vary. Thus, the most expensive gasoline is in California: in Los Angeles and San Francisco the cost is about $4 per gallon. For comparison, in Texas it is $1.95. In some cities, the price is completely low: for example, in Houghton (Michigan), the cost per gallon was once only $0.47.

If the gas station is located far from the city, the price increases accordingly. For example, at gas stations near Antelope Canyon the cost rises to $6.

Statistics say that the price varies depending on the month. So, the lowest cost is usually in the summer - $0.68. The highest is in the fall (about 0.75 per liter).

You can also note that they tend not only to grow, but also to fall, which is quite understandable because the market is developing. Residents of Russia, for example, should not expect prices to fall due to the colossal scale of corruption in the oil industry and the dominance of a single company in the market.

The price an American driver pays for gasoline already includes all taxes, so no additional payments will be required.

What makes up the cost of gasoline in the USA in comparison with Russia.

General information

Volume is the space occupied by a substance or object. Volume can also refer to the free space inside a container. Volume is a three-dimensional quantity, unlike, for example, length, which is two-dimensional. Therefore, the volume of flat or two-dimensional objects is zero.

Volume units

Cubic meter

The SI unit of volume is the cubic meter. The standard definition of one cubic meter is the volume of a cube with edges one meter long. Derived units such as cubic centimeters are also widely used.

Liter

The liter is one of the most commonly used units in the metric system. It is equal to the volume of a cube with edges 10 cm long:
1 liter = 10 cm × 10 cm × 10 cm = 1000 cubic centimeters

This is the same as 0.001 cubic meters. The mass of one liter of water at a temperature of 4°C is approximately equal to one kilogram. Milliliters, equal to one cubic centimeter or 1/1000 of a liter, are also often used. Milliliter is usually denoted as ml.

Jill

Gills are units of volume used in the United States to measure alcoholic beverages. One jill is five fluid ounces in the British Imperial system or four in the American system. One American jill is equal to a quarter of a pint or half a cup. Irish pubs serve strong drinks in portions of a quarter jill, or 35.5 milliliters. In Scotland, portions are smaller - one fifth of a jill, or 28.4 milliliters. In England, until recently, portions were even smaller, just one-sixth of a jill or 23.7 milliliters. Now, it’s 25 or 35 milliliters, depending on the rules of the establishment. The owners can decide for themselves which of the two portions to serve.

Dram

Dram, or drachma, is a measure of volume, mass, and also a coin. In the past, this measure was used in pharmacy and was equal to one teaspoon. Later, the standard volume of a teaspoon changed, and one spoon became equal to 1 and 1/3 drachms.

Volumes in cooking

Liquids in cooking recipes are usually measured by volume. Bulk and dry products in the metric system, on the contrary, are measured by mass.

Tea spoon

The volume of a teaspoon is different in different measurement systems. Initially, one teaspoon was a quarter of a tablespoon, then - one third. It is the latter volume that is now used in the American measurement system. This is approximately 4.93 milliliters. In American dietetics, the size of a teaspoon is 5 milliliters. In the UK it is common to use 5.9 milliliters, but some diet guides and cookbooks use 5 milliliters. The size of a teaspoon used in cooking is usually standardized in each country, but different sizes of spoons are used for food.

Tablespoon

The volume of a tablespoon also varies depending on the geographic region. So, for example, in America, one tablespoon is three teaspoons, half an ounce, approximately 14.7 milliliters, or 1/16 of an American cup. Tablespoons in the UK, Canada, Japan, South Africa and New Zealand also contain three teaspoons. So, a metric tablespoon is 15 milliliters. A British tablespoon is 17.7 milliliters, if a teaspoon is 5.9, and 15 if a teaspoon is 5 milliliters. Australian tablespoon - ⅔ ounce, 4 teaspoons, or 20 milliliters.

Cup

As a measure of volume, cups are not defined as strictly as spoons. The volume of the cup can vary from 200 to 250 milliliters. A metric cup is 250 milliliters, and an American cup is slightly smaller, approximately 236.6 milliliters. In American dietetics, the volume of a cup is 240 milliliters. In Japan, cups are even smaller - only 200 milliliters.

Quarts and gallons

Gallons and quarts also have different sizes depending on the geographic region where they are used. In the Imperial system of measurement, one gallon is equal to 4.55 liters, and in the American system of measurements - 3.79 liters. Fuel is generally measured in gallons. A quart is equal to a quarter of a gallon and, accordingly, 1.1 liters in the American system, and approximately 1.14 liters in the Imperial system.

Pint

Pints ​​are used to measure beer even in countries where the pint is not used to measure other liquids. In the UK, milk and cider are measured in pints. A pint is equal to one-eighth of a gallon. Some other countries in the Commonwealth of Nations and Europe also use pints, but since they depend on the definition of a gallon, and a gallon has a different volume depending on the country, pints are also not the same everywhere. An imperial pint is approximately 568.2 milliliters, and an American pint is 473.2 milliliters.

Fluid ounce

An imperial ounce is approximately equal to 0.96 US ounces. Thus, an imperial ounce contains approximately 28.4 milliliters, and an American ounce contains approximately 29.6 milliliters. One US ounce is also approximately equal to six teaspoons, two tablespoons, and one eighth cup.

Volume calculation

Liquid displacement method

The volume of an object can be calculated using the fluid displacement method. To do this, it is lowered into a liquid of a known volume, a new volume is geometrically calculated or measured, and the difference between these two quantities is the volume of the object being measured. For example, if when you lower an object into a cup with one liter of water, the volume of the liquid increases to two liters, then the volume of the object is one liter. In this way, you can only calculate the volume of objects that do not absorb liquid.

Formulas for calculating volume

The volume of geometric shapes can be calculated using the following formulas:

Prism: the product of the area of ​​the base of the prism and the height.

Rectangular parallelepiped: product of length, width and height.

Cube: length of an edge to the third power.

Ellipsoid: product of semi-axes and 4/3π.

Pyramid: one third of the product of the area of ​​the base of the pyramid and the height. Post a question in TCTerms and within a few minutes you will receive an answer.
