We will 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 abbreviated form SI).

From time to time the kilogram could be written as kilogramme. The symbol of the kilogram is kg.

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

Then, in 1889 the kilogram was defined by the International Prototype of the Kilogram (in abbreviated form IPK). The IPK was prepared of 90% platinum and 10 % iridium. The IPK was in use until 2019, when it was switched 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 0.001 tonne. It is also divided to 100 decagrams and 1000 grams.

The international avoirdupois pound has no descriptive definition. It is equal 0.45359237 kilograms. One avoirdupois pound can be divided into 16 avoirdupois ounces and 7000 grains.

The avoirdupois pound was enforced in the Weights and Measures Act 1963. The definition of the pound was placed 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.”
