## 20.57 kg to lbs

Before we get to the more practical part - that is 20.57 kg how much lbs calculation - we are going to tell you a little bit of theoretical information about these two units - kilograms and pounds. So let’s move on.

## 20.57 kgs in pounds

We will begin with the kilogram. The kilogram is a unit of mass. It is a basic unit in a metric system, formally known as International System of Units (in short form SI).

At times the kilogram is written as kilogramme. The symbol of this unit 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 not complicated but totally impractical to use.

Later, in 1889 the kilogram was defined by 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 used until 2019, when it was switched by another definition.

Nowadays 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 to 100 decagrams and 1000 grams.

You learned a little bit about kilogram, so now let’s move on to the pound. The pound is also a unit of mass. It is needed to emphasize that there are not only one kind of pound. What are we talking about? For instance, there are also pound-force. In this article we want to centre only on pound-mass.

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

The international avoirdupois pound has no descriptive definition. It is equal 0.45359237 kilograms. One avoirdupois pound is divided into 16 avoirdupois ounces or 7000 grains.

The avoirdupois pound was enforced 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.”
