The kilogram was defined first time in 1795. The kilogram was defined as the mass of one liter of water. First definition was not complicated but totally impractical to use.

Then, in 1889 the kilogram was described using the International Prototype of the Kilogram (in abbreviated 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 substituted by another definition.

Today 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 into 100 decagrams and 1000 grams.
