This whole article is dedicated to kilogram to pound conversion - theoretical and also practical. It is also needed/We also want to emphasize that all this article is dedicated to a specific number of kilograms - that is one kilogram. So if you need to learn more about 57.21 kg to pound conversion - keep reading.

Before we go to the more practical part - that is 57.21 kg how much lbs conversion - we will tell you few theoretical information about these two units - kilograms and pounds. So let’s move on.

57.21 kgs in pounds

We will 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 can be written as kilogramme. The symbol of the kilogram is kg.

First definition of a kilogram was formulated 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 using the International Prototype of the Kilogram (in short form IPK). The International Prototype of the Kilogram was prepared of 90% platinum and 10 % iridium. The International Prototype of the Kilogram was in use until 2019, when it was substituted by another 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 exactly 0.001 tonne. It can be also divided into 100 decagrams and 1000 grams.

57.21 kilogram to pounds

You know a little about kilogram, so now we can go to the pound. The pound is also a unit of mass. We want to underline that there are not only one kind of pound. What does it mean? For instance, there are also pound-force. In this article we want to centre only on pound-mass.

The pound is in use in the British and United States customary systems of measurements. To be honest, this unit is used also in other systems. The symbol of the pound is lb or “.

There is no descriptive definition of the international avoirdupois pound. It is defined as exactly 0.45359237 kilograms. One avoirdupois pound can be divided into 16 avoirdupois ounces and 7000 grains.

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