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

Then, in 1889 the kilogram was defined 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.

The new 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 is also divided into 100 decagrams and 1000 grams.
