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

Then, in 1889 the kilogram was defined by the International Prototype of the Kilogram (in abbreviated form IPK). The IPK was prepared of 90% platinum and 10 % iridium. The IPK was in use until 2019, when it was replaced 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 0.001 tonne. It can be also divided into 100 decagrams and 1000 grams.
