More about mass

General information

Mass is the property of physical bodies to resist acceleration. Mass, unlike weight, does not change depending on the environment and does not depend on the gravitational force of the planet on which this body is located. Mass m determined using Newton's second law, according to the formula: F = ma, Where F- this is strength, and a- acceleration.

Mass and weight

The word “weight” is often used in everyday life when people talk about mass. In physics, weight, in contrast to mass, is a force acting on a body due to the attraction between bodies and planets. Weight can also be calculated using Newton's second law: P= mg, Where m is the mass, and g- acceleration of gravity. This acceleration occurs due to the gravitational force of the planet near which the body is located, and its magnitude also depends on this force. The acceleration of free fall on Earth is 9.80665 meters per second, and on the Moon it is approximately six times less - 1.63 meters per second. Thus, a body weighing one kilogram weighs 9.8 newtons on Earth and 1.63 newtons on the Moon.

Gravitational mass

Gravitational mass shows what gravitational force acts on a body (passive mass) and what gravitational force the body acts on other bodies (active mass). When increasing active gravitational mass body, its force of attraction also increases. It is this force that controls the movement and location of stars, planets and other astronomical objects in the universe. Tides are also caused by the gravitational forces of the Earth and Moon.

With increase passive gravitational mass the force with which the gravitational fields of other bodies act on this body also increases.

Inert mass

Inertial mass is the property of a body to resist movement. It is precisely because a body has mass that a certain force must be applied to move the body from its place or change the direction or speed of its movement. The greater the inertial mass, the greater the force required to achieve this. Mass in Newton's second law is precisely inertial mass. The gravitational and inertial masses are equal in magnitude.

Mass and relativity

According to the theory of relativity, gravitating mass changes the curvature of the space-time continuum. The greater the mass of a body, the stronger the curvature around this body, therefore, near bodies of large mass, such as stars, the trajectory of light rays is bent. This effect in astronomy is called gravitational lenses. On the contrary, far from large astronomical objects (massive stars or their clusters called galaxies), the movement of light rays is linear.

The main postulate of the theory of relativity is the postulate about the finiteness of the speed of propagation of light. Several interesting consequences follow from this. Firstly, one can imagine the existence of objects with such a large mass that the second cosmic velocity of such a body will be equal to the speed of light, i.e. no information from this object will be able to reach the outside world. Such cosmic objects in the general theory of relativity are called “black holes” and their existence has been experimentally proven by scientists. Secondly, when an object moves at near-light speed, its inertial mass increases so much that local time inside the object slows down compared to time. measured by stationary clocks on Earth. This paradox is known as the “twin paradox”: one of them goes into space flight at near-light speed, the other remains on Earth. Upon returning from the flight twenty years later, it turns out that the twin astronaut is biologically younger than his brother!

Units

Kilogram

In the SI system, mass is expressed in kilograms. The kilogram is determined based on the exact numerical value of Planck's constant h, equal to 6.62607015×10⁻³⁴, expressed in J s, which is equal to kg m² s⁻¹, with the second and meter being determined by exact values c and Δ ν Cs. The mass of one liter of water can be approximately considered equal to one kilogram. The derivatives of kilogram, gram (1/1000 of a kilogram) and ton (1000 kilograms) are not SI units, but are widely used.

Electron-volt

Electronvolt is a unit for measuring energy. It is usually used in the theory of relativity, and energy is calculated using the formula E=mc², where E- this is energy, m- mass, and c- speed of light. According to the principle of equivalence of mass and energy, the electronvolt is also a unit of mass in the system of natural units, where c is equal to unity, which means mass equals energy. Electrovolts are mainly used in nuclear and atomic physics.

Atomic mass unit

Atomic mass unit ( A. eat.) is intended for masses of molecules, atoms, and other particles. One a. e.m. is equal to 1/12 the mass of a carbon nuclide atom, ¹²C. This is approximately 1.66 × 10 ⁻²⁷ kilograms.

Slug

Slugs are used primarily in the British Imperial system in Great Britain and some other countries. One slug is equal to the mass of a body that moves with an acceleration of one foot per second per second when a force of one pound-force is applied to it. This is approximately 14.59 kilograms.

Solar mass

Solar mass is a measure of mass used in astronomy to measure stars, planets and galaxies. One solar mass is equal to the mass of the Sun, that is, 2 × 10³⁰ kilograms. The mass of the Earth is approximately 333,000 times less.

Carat

Carats measure the weight of precious stones and metals in jewelry. One carat is equal to 200 milligrams. The name and the size itself are associated with the seeds of the carob tree (in English: carob, pronounced “carob”). One carat used to be equal to the weight of the seed of this tree, and buyers carried their seeds with them to check whether they were being deceived by sellers of precious metals and stones. The weight of a gold coin in Ancient Rome was equal to 24 carob seeds, and therefore carats began to be used to indicate the amount of gold in the alloy. 24 carat is pure gold, 12 carat is half gold alloy, and so on.

Grand

The grain was used as a measure of weight in many countries before the Renaissance. It was based on the weight of grains, mainly barley, and other popular crops at the time. One grain is equal to about 65 milligrams. This is a little more than a quarter of a carat. Until carats became widespread, grains were used in jewelry. This measure of weight is still used to this day to measure the mass of gunpowder, bullets, arrows, and gold foil in dentistry.

Other units of mass

In countries where the metric system is not adopted, the British Imperial system is used. For example, in the UK, USA and Canada, pounds, stones and ounces are widely used. One pound is equal to 453.6 grams. Stones are used mainly only to measure human body weight. One stone is approximately 6.35 kilograms or exactly 14 pounds. Ounces are primarily used in cooking recipes, especially for foods in small portions. One ounce is 1/16 of a pound, or approximately 28.35 grams. In Canada, which formally adopted the metric system in the 1970s, many products are sold in rounded imperial units, such as one pound or 14 fluid ounces, but are labeled with weight or volume in metric units. In English, such a system is called “soft metric” (English). soft metric), in contrast to the “rigid metric” system (eng. hard metric), in which the rounded weight in metric units is indicated on the package. This image shows "soft metric" food packaging with weight in metric units only and volume in both metric and imperial units.

Do you find it difficult to translate units of measurement from one language to another? Colleagues are ready to help you. Post a question in TCTerms and within a few minutes you will receive an answer.

We, in Russia, are accustomed to dealing with kilograms, but in countries where braid is developed and manufactured, there is a different measurement system in pounds (lb). Therefore, we often indicate the thickness, or more precisely, the diameter of the braid in millimeters on boxes and spools of fishing line. And, in other countries, the strength of a fishing line is measured not by its thickness and diameter, but by its breaking load in pounds, i.e. lb. And there’s nothing you can do about it, you just need to figure it out and understand how to convert pounds to kg and the problems with misunderstanding will disappear.

Everything is logical with the braided line

As you know, Western people are more pragmatic than us. And few people can dispute this. So, in the marking of fishing gear and accessories, they go towards convenience and practicality.

Agree that it is much more convenient to see the load in pounds, and for them, this is a standard measure of weight, and to estimate whether such a braid is suitable for us. Depending on what kind of fish we will catch and in what conditions.

In Russia, it is customary to name the diameter of a fishing line in millimeters, and when buying braided line, you need to estimate what power in kilograms such a fishing line will have. For those who have been interested in spinning for many years, this is not a problem, but for beginners, such markings can become a serious obstacle to choosing the right braid. What to do in such a situation?

The principle of converting lb to kg

This is more familiar to us. In general, lb is a weight meter. This is about 454 grams, or 0.45359237 kg. And then the most ancient science - mathematics - comes into its own. Just take and multiply the number of pounds and kg.

This results in a correspondence between diameter and lb:

6 lb = 2.72 kg

8 lb = 3.63 kg

10 lb = 4.54 kg

20 lb = 9.07 kg

30 lb = 13.61 kg

Following this principle, it is easy to recalculate the load in kilograms. But converting lb to millimeters is much more difficult. Because different fishing line with the same diameter will have different power. And for each brand of fishing line, the thickness, with the same breaking load, will be completely different.

That is, converting the breaking load into diameter becomes completely useless and even meaningless. If the spool reel clearly states the breaking load in lb. You need to use it and not bother yourself with different translations in mm.

Conversion tables for feet and inches to centimeters (height) and pounds to kilograms (weight).

Hello, my dear readers! We all know the “golden rule” of an Internet shopaholic:

“Carefully study the reviews of a new brand or product before you buy it!”

How often have you seen reviews like this:

"I'm 5′ 8″ 180 and the large was huge on me, the length is above the ankles but well below the knee. I’ve always had a small waist for my size even after gaining 25lbs over the..."

« I'm a very large woman ( 5'6″ tall and 260lbs. Size 48DDD chest. I wanted a long dress that was basic and comfy vs a “moo-moo” This thing fit the bill. Of… «

“I bought one in every color! I am petite ( 5′ 2″) and I like that it comes right across the tops of my feet! Pairs perfectly with..."

What do these numbers, unusual for the Belarusian eye, mean? Just height and weight (yes, not parameters (90-60-90), as is customary here, but weight).

To measure length, Americans use feet And inches, and for measuring weight - pounds. So, the first review given as an example was written by a person with a height of 173 cm and a weight of 82 kg (5′ 8″ 180).

If you, like me, do not like to study reviews of happy and not so American customers with a calculator in hand, then here is a nice table for converting feet and inches to centimeters to help us all:

If you need a different length that does not fit in the table, you will still have to arm yourself with a calculator:

1 Foot = 30.48 cm

1 Inch = 2.54 cm

I still haven’t learned how to navigate clothing sizes based on a person’s weight. But what if you are the guru of this? Then this table for converting pounds to kilograms will help you:

1 Pound = 0.454 kg

Here is such a short, but, I hope, useful article.)))

P.S. Ask all your questions in the comments to this article - I will be happy to answer them! And don't forget SHOPOKlang so you don't miss new interesting articles!

The weight measure pound, pound, pondus is little known to residents of Russia, since it is mainly used in England and English-speaking countries, and because of this, converting weight units kilogram to pound and back weight in pounds to kilograms causes a certain problem. Pound (pound) comes from the Latin word pondus, which means weight, weight and is used to measure units of weight and mass. In English-speaking countries, the Latin word libra was used before the introduction of pounds pondus, but the abbreviation lb (libra) is still used in some places. Also, in a number of countries with English, there is a monetary unit called the pound, such as pound sterling, which also comes from the Latin word libra. The weight unit pound (pound pondus), which is now used in America and England, is equal to 16 ounces of weight or in the metric system weight 453.592374495300 grams. Our script for converting weights from a pound (pound pondus) to kilograms and should not be confused with the troy pound, which is used as a pharmaceutical unit of weight in England, is equal to 12 troy ounces or in the metric system 373.241718913976 grams. Or with weight measures in pounds (pound pondus), which were previously used in Russia, Sweden and Austria, when in Russia before the revolution the weight measure pound was equal to 32 lots or 409.512030787770 grams of the metric system, pound used in Sweden (Swedish pound) was equal to 425 grams, and the Austrian pound in weight was equal to 560.01 grams of the metric system. Also in some countries you can come across the term metric pound, which is written in Holland as pond, in Germany as Pfund, and in France as livre, while everywhere the metric pound is equal to 0.5 kilograms or 500 grams. Concluding our description of the weight measure pound (pound pondus), let us once again recall that our script converts kilograms into pounds (pondus) and vice versa, which are used as a measure of weight in England and America and a pound is equal to 453.592374495300 grams, rounded to 4 decimal places .

It is no secret that everything fishing in the world is measured in measures unknown to the average Russian person. Particular confusion arises from the fact that sometimes different names turn out to be actually the same thing, and one can argue for a long time about how many libres are in a pound. And then there is the Roman measure, so everything there is generally not the same as it is today.

Line break test, line test for rods and reels are measured in Librach... :) Actually no - in Pounds. The confusion arises from the fact that the abbreviation for pound is lb(or if there are a lot of pounds lbs), what we used to call libra.

1 pound (1 lb) - 0.453 592 37 kg or 453.59237 g. Roughly we can count - half a kilo, which is convenient for the first mental estimate, given that such an estimate will be overkill by about 10%. And for a quick and accurate determination there is a table (rounded):

lb	1	2	3	4	5	6	7	8	9	10
kg	0.450	0.900	1.360	1.815	2.270	2.720	3.175	3.630	4	4.550

lb	12	14	16	18	20
kg	5.450	6.350	7.250	8.160	9

Historical reference: The Roman pound is Roman Libra, where the reduction came from. The weight in grams of the Roman pound/libra is different, so I won’t even give it.

Lure test for fishing rods, bait weight, float load test are measured in Ounces(abbreviated oz, from ounce).

1 ounce (1 oz) - 28.349 523 125 g. An ounce is essentially 1/16 of a pound.

Traditionally, the weight in an ounce is written on the boxes of wobblers and squeezed out on jig heads not in absolute numbers, but in fractions of 1/2, 3/5, 5/8 oz, which again completely confuses the brain function of an ordinary Russian with a secondary and higher education. Therefore, the table (grams are given in two approximations for convenience):

oz	1/32	1/24	1/16	1/12	1/10	1/8	1/7	1/6	1/5
G	0,89 1	1.18 1.2	1.77 2	2.36 2.5	2.84 3	3,54 3,5	4,05 4	4,73 5	5,67 6

oz	1/4	1/3	3/8	1/2	5/8	3/4	7/8	1	2	3	4	5	6
G	7,09 7	9,45 9,5	10,63 10 - 11	14,18 14	17,72 18	21,26 21	24,8 25	28,35 28	56,7 57	85,05 85	113,4 113	141,75 142	170,1 170

Sometimes you see the following inscriptions: 1-1/2 oz is actually 1/4 oz, and not (1 oz - 1/2 oz) = 1/2 oz. This is the arithmetic.

Historical reference: The modern common ounce is Ounce avoirdupois, 1/16 of an avoirdupois pound. Is there some more Troy ounce, which is used in jewelry and banking. And there is Roman ounce. A troy and Roman ounce is 1/12 of its own pounds. And of course, all these ounces are not equal to each other, so we don’t want to know and generally forget about them until someone is given a spoon made of pure gold, then we can show off with happiness and count in troy ounces, because it’s not hala-bola, but gold .

Postscript: volumes of liquids are also measured in ounces, but there is no way to change our tradition of measuring the same liquid in grams. Because “well, they’re pissing” and “sir, add 2 ounces, please” are two big differences: one is filled with meaning, and the second may be the reason for an unreasonable message.
