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

Sometimes the kilogram is written as kilogramme. The symbol of the kilogram is kg.

First definition of a kilogram was formulated in 1795. The kilogram was described as the mass of one liter of water. First definition was simply but difficult 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 used until 2019, when it was substituted by another 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 exactly 0.001 tonne. It can be also divided into 100 decagrams and 1000 grams.

The avoirdupois pound was enforced in the Weights and Measures Act 1963.
