## 21.04 kg to lbs

Before we get to the practice - this is 21.04 kg how much lbs conversion - we will tell you few theoretical information about these two units - kilograms and pounds. So we are starting.

## 21.04 kgs in pounds

We are going to begin with the kilogram. The kilogram is a unit of mass. It is a base unit in a metric system, known also as International System of Units (in abbreviated form SI).

Sometimes the kilogram could be written as kilogramme. The symbol of the kilogram is kg.

First definition of a kilogram was formulated in 1795. The kilogram was defined as the mass of one liter of water. First definition was simply but totally impractical to use.

Then, in 1889 the kilogram was described using the International Prototype of the Kilogram (in short form IPK). The International Prototype of the Kilogram was made of 90% platinum and 10 % iridium. The International Prototype of the Kilogram was in use until 2019, when it was replaced by a new definition.

Today the definition of the kilogram is based on physical constants, especially Planck constant. Here is the official definition: “The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10−34 when expressed in the unit J⋅s, which is equal to kg⋅m2⋅s−1, where the metre and the second are defined in terms of c and ΔνCs.”

One kilogram is 0.001 tonne. It could be also divided to 100 decagrams and 1000 grams.

You know a little about kilogram, so now let’s move on to the pound. The pound is also a unit of mass. It is needed to point out that there are more than one kind of pound. What does it mean? For instance, there are also pound-force. In this article we want to concentrate only on pound-mass.

The pound is in use in the British and United States customary systems of measurements. Naturally, this unit is in use also in another systems. The symbol of the pound is lb or “.

There is no descriptive definition of the international avoirdupois pound. It is equal 0.45359237 kilograms. One avoirdupois pound is divided to 16 avoirdupois ounces and 7000 grains.

The avoirdupois pound was enforced in the Weights and Measures Act 1963. The definition of this unit was given in first section of this act: “The yard or the metre shall be the unit of measurement of length and the pound or the kilogram shall be the unit of measurement of mass by reference to which any measurement involving a measurement of length or mass shall be made in the United Kingdom; and- (a) the yard shall be 0.9144 metre exactly; (b) the pound shall be 0.45359237 kilogram exactly.”
