We are going to begin with the kilogram. The kilogram is a unit of mass. It is a basic unit in a metric system, formally known as International System of Units (in abbreviated form SI).

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

Firstly, the definition of a kilogram was formulated in 1795. The kilogram was described as the mass of one liter of water. First definition was not complicated but hard to use.

Then, in 1889 the kilogram was described using the International Prototype of the Kilogram (in short form IPK). The IPK was made of 90% platinum and 10 % iridium. The IPK was used until 2019, when it was switched by another definition.

Nowadays the 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 equal 0.001 tonne. It can be also divided into 100 decagrams and 1000 grams.
