Sometimes the kilogram can be written as kilogramme. The symbol of this unit is kg.

Firstly the kilogram was defined in 1795. The kilogram was defined as the mass of one liter of water. This definition was simply but difficult to use.

Later, 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 used until 2019, when it was replaced by a new definition.

Today 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 exactly 0.001 tonne. It is also divided into 100 decagrams and 1000 grams.
