## 21.01 kg to lbs

Before we move on to the more practical part - that is 21.01 kg how much lbs conversion - we want to tell you a little bit of theoretical information about these two units - kilograms and pounds. So let’s move on.

## 21.01 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, formally known as International System of Units (in short form SI).

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

The kilogram was defined first time in 1795. The kilogram was described as the mass of one liter of water. First definition was simply but impractical to use.

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

Nowadays the definition of the kilogram is based on physical constants, especially Planck constant. The official definition is: “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.

## 21.01 kilogram to pounds

You learned some information about kilogram, so now we can move on to the pound. The pound is also a unit of mass. We want to emphasize that there are not only one kind of pound. What does it mean? For example, there are also pound-force. In this article we want to concentrate only on pound-mass.

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

The international avoirdupois pound has no descriptive definition. It is defined as exactly 0.45359237 kilograms. One avoirdupois pound could be divided to 16 avoirdupois ounces or 7000 grains.

The avoirdupois pound was implemented in the Weights and Measures Act 1963. The definition of the pound was written 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.”
