Is the kilogram a unit of mass or a unit of force?

1. The kilogram is the kilogram, which is a unit of mass and is used to express the amount of material contained in an object.

2. The unit of force is Newton, on the earth, the magnitude of the force generated by 1kg is 10n3, in life, we simply say how many kilograms the weight of the object is, although this is not very rigorous, but it has been accepted by the public, and the measure word n is only mentioned in academia.

4. In engineering, kilograms are often used to express pressure, for example, 6 kilograms of steam, in fact, this is an abbreviation, the full name should be 6 kilograms of cm2 of steam, which is equivalent to the pressure of megapascals.

Hope mine can help you.

The kilogram is a unit of mass.

Transformation of units of mass: The situation of units of mass and length was similar in ancient times, and there were many forms. For example:

In Persia, karasha is used as a unit of mass, about kilograms, and in Egypt it is used as a gedet, about grams. China's Qin Dynasty weights and measures system stipulates: 1 stone 4 jun, 1 jun 30 catties, 1 jin 16 taels.

Compared with the modern International System of Units, 1 catty is about 0 256 kilograms. In the imperial system, pounds, ounces, drams, and grains are used as units: 1 pound, 16 ounces, 265 pounds, and 7,000 grains.

The British Empire used to make pound primitives from pure platinum, which were pure platinum cylinders about inches high and inches in diameter.

The original unit of kilogram mass was derived from the metre, a unit of length adopted in France at the end of the 18th century. The mass of 1 cubic decimeter of pure water at its maximum density (temperature of about 4 degrees Celsius) is set at 1 kilogram.

In 1799, while France was making platinum rice originals, it also made a platinum kilogram benchmark, which was kept in the Paris Archives.

It was later found that this benchmark was not exactly equal to the mass of 1 cubic decimeter of maximum density pure water, but to 1 000028 cubic decimeter. Therefore, after the 1875 Metric Convention Conference, the kilogram prototype was also made from an alloy containing 90% platinum and 10% iridium, and a total of three were made, and one of them was selected as the international kilogram prototype after comparison with the platinum kilogram prototype preserved by the Paris Archives. This international kilogram prototype has been carefully kept in a special location by the experts of the International Bureau of Weights and Measures, covered with three layers of glass, and the outermost glass cover is pumped into a semi-vacuum to prevent the ingress of air and impurities.

Subsequently, 40 platinum-iridium alloy cylinders were copied and compared with the international prototype kilogram and distributed to Member States as national benchmarks. Like the rice prototype, the kilogram prototype is also subject to periodic verification to ensure the stability and reliability of the quality benchmark.

In the modern definition, 1 kilogram is equal to 2 catties, which is also equal to 1000 grams. The unit of force is Newton.

Abbreviated as cow unit symbol: n

The kilogram is a unit of mass, because in people's lives and **, mass is also used to be called weight. Kilogram and kilogram are synonymous!

However, in the hydraulic industry, many people say how much "kilogram force", which is the traditional name of pressure, 1 "kilogram force" = .

Therefore, the kilogram is the unit of mass in SIPs!!

It is a unit of mass, and sometimes the weight of the force is measured in kilograms, for example, the strength of a boxer's punch is 200 kilograms, and it is said that he can knock down an object with a mass of 200 kilograms with a single punch. But the kilogram is still a unit of mass.

The kilogram is a unit of mass.

Kilogram generally refers to kilograms, 1 kilogram = 1 kilogram.

The kilogram (symbol kg) is the basic unit of measurement of mass in the International System of Units, and the kilogram is also one of the most commonly used basic units in daily life. One kilogram is defined as the mass of the international kilogram prototype, which is almost the same weight as one liter of water.

Of course, it is the unit of mass, and the unit of force is only n (newtons).

Kilograms are the unit of force! It is also a unit of quality! Haha,,, it doesn't matter what he is, it doesn't seem to matter, right?!

The kilogram is a metric unit of measurement. The kilogram is one of the most commonly used basic units in daily life and touches every aspect of people's lives. One kilogram is equal to one kilogram, which is two catties in China.

I. Translation of International Units.

1 kilogram = metric ton (or "ton").

1 kg = 1,000 grams.

1 kg = 1,000,000 mg.

1 kilogram = 1,000,000,000 micrograms.

1 kg = 2 catties.

1 kg = 1 kg.

1 kg = 20 taels.

Second, the relevant conversion of catties.

The modern Jin system is converted to the metric system as follows according to the usage habits of various places:

1 jin in Chinese mainland is equal to 500 grams (g).

Hong Kong and Macau 1 catty is about equal to 605 (g).

Taiwan 1 Jin is equal to 600 grams (g).

At present, the law in Hong Kong stipulates that one catty is equal to 100 quintals or 16 taels, i.e. grams (g).

Taiwanese system commonly used in Taiwanese markets: 1 catty = 600 grams. However, Kinmen is close to Matsu in Fujian Province and does not use taijin, and the so-called jin is 1 jin = 500 grams.

China's legal unit of measurement adopts the International System of Units, and its internal uses include:

The basic unit of the International System of Units.

SI Auxiliary Units.

An exported unit with a specialized name in the International System of Units.

A Chinese legal unit of measurement that can be used in conjunction with SI units.

A unit in the form of a combination of the above units.

Decimal multiples and fractional units composed of prefixes and above units.

The kilogram is a unit of weight, and it has no additional unit name. The kilogram is a more commonly used unit of weight in China, which is a metric unit of measurement. One kilogram is equal to one kilogram.

The unit of weight has a long history, in ancient times, countries had their own units of measurement, the ancient Chinese unit of weight, jun: thirty catties is a jun; Ten taels weigh one baht, twenty-four baht weighs one tael, and sixteen taels weigh one catty.

China has a specific unit of measurement, catty, the international unit of measurement, kilograms, tons, the United States, Britain pound and so on.

There is no "jin" in the international standard unit, which is a unit in our country.

Secondly, units such as "jin" and "kilogram" are obviously weight units in physics, and are by no means mass units, please understand the difference between mass and weight. Again, from the perspective of law and life, China's law clearly stipulates that units such as "catty" and "kilogram" can be regarded as quality units and used on various occasions, and quality = weight is legally equivalent and has legal effect.

Also known as kilograms, it is the international basic unit of mass with the symbol kg.

In 1791, it was stipulated that the mass of pure water in 1 cubic decimeter at 4 o'clock, and the original instrument made of platinum-iridium alloy was preserved in Paris, and later called the international kilogram prototype.

On November 16, 2018, the 26th International Conference on Weights and Measures (CGPM) unanimously adopted Resolution 1 on "Revision of the International System of Units (SI)" by a vote of all member countries, including China. According to the resolution, the definition of the four SI base units of kilograms, amperes, kelvins and moles will be changed to constants, which will take effect on May 20, 2019.

1 kilogram will be defined as "the unit of mass corresponding to Planck's constant". The principle is to convert the mechanical force required to move an object with a mass of 1 kg into an electromagnetic force that can be expressed by Planck's constant, and then calculate the mass by the mass-energy conversion formula.

Unit Conversion. 1 kg = ton.

1 kg = 1,000 grams.

1 kg = 1,000,000 mg.

1 kilogram = 1,000,000,000 micrograms.

The above content refers to Encyclopedia - Units of Weight.

The unit of kilogram is kg. The kilogram is one of the most commonly used basic units in daily life and touches every aspect of people's lives. The kilogram is a metric unit of measurement, and one kilogram is equal to one kilogram, which is equivalent to two catties in China.

In fact, a kilogram is a kilogram. When an object with a mass of one kilogram is subjected to a force of one newton, it gains an acceleration of one meter per square second. The kilogram is the only basic unit with an SI prefix, and the only SI unit that still uses artifacts as its definition.

In addition, the international common mass units are: milligrams, grams, tons, etc.

The symbol kg is the kilogram, which is the basic unit of measurement of mass in the International System of Units, and the kilogram is also one of the most commonly used basic units in daily life. A kilogram is defined as a unit of mass when Planck's constant lasts, almost as much as a liter of water. The kilogram is the only basic unit with an SI prefix.

The kilogram unit is kilograms. Analysis: 1 kilogram is equal to 1 kilogram. The sail is in kilograms.

Mass unit conversion1) 1 kg = ton.

2) 1 kg = 1,000 grams.

3) 1 kg = 1,000,000 mg.

4) Repentance to make 1 kilogram = 1,000, such as 000,000 micrograms.

5) Metric: 1 Jin = 10 taels = 100 money.

6) Municipal system: 1 catty = 16 taels = 160 money.

7) 1 tael = kilogram = 50 grams.

What is the unit of weight greater than a ton, and the unit of mass that is larger than a "ton" is the mass of the sun. Solar mass is a unit of mass used to measure stars or large celestial bodies such as galaxies. Its size is equal to the total mass of the Sun, which is about kilograms.

It can be represented as m by the unit symbol; The mass of the Sun is 330,000 times that of the Earth. The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

kg is the unit of mass, kilogram. Kilograms (kg), grams (g) and milligrams (mg) are internationally used units of mass, one kilogram is equal to 1000 grams, one gram is equal to 1000 milligrams, 1 kilogram = 1 kilogram in daily life.

According to the regulations, 1 kg = 500 grams, and because 1 kg = 1 kg = 1000 grams, 1 kg is equal to 2 catties, that is, 1 kg = 2 catties. In addition, one kilogram is equal to 20 city taels, and people often say that one pound is actually 10 city taels.

Unit conversion: 1 kilogram = metric ton (or"Tons")。

1 kg = 1,000 grams.

1 kg = 1,000,000 mg.

1 kilogram = 1,000,000,000 micrograms.

1 kg = 2 catties.

1 kg = 1 kg.

1 kg = 20 taels.

Mass is the amount of matter contained in an object, the unit is grams, kilograms, and so on, and the mass determines the inertia.

Weight is generated by the acceleration of gravity acting on a mass object, so it is not only related to mass, but also related to gravity, but generally speaking, in an environment with mass and gravity (such as the earth's surface), weight and mass are simply proportional, which is why weight and mass are often confused.

Kilogram force is kilogram force, which is a common unit of force. Force is one of the basic concepts in mechanics and is the external cause that causes an object to change its state of motion or deformity. In Tanzai dynamics, it is equal to the product of the mass of the object and the acceleration.

Force is the action of an object on an object, so the force is the nucleus that appears as a change of faith. There is force and force. The force generated by the interaction between two objects through different forms, such as attraction, relative motion, deformation, etc., is called the force.
