## 30.51 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, that is International System of Units (in short form SI).

Sometimes the kilogram can be written as kilogramme. The symbol of this unit 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 not complicated but impractical to use.

Then, in 1889 the kilogram was described 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 IPK was in use until 2019, when it was substituted by another definition.

Nowadays the definition of the kilogram is build 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 equal 0.001 tonne. It could be also divided into 100 decagrams and 1000 grams.
