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

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

Firstly the kilogram was defined in 1795. The kilogram was described as the mass of one liter of water. First definition was simply but totally impractical to use.

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

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

The avoirdupois pound was implemented in the Weights and Measures Act 1963. The definition of the pound was given in first section of this act: “The yard or the metre shall be the unit of measurement of length and the pound or the kilogram shall be the unit of measurement of mass by reference to which any measurement involving a measurement of length or mass shall be made in the United Kingdom; and- (a) the yard shall be 0.9144 metre exactly; (b) the pound shall be 0.45359237 kilogram exactly.”
