We will start with the kilogram. The kilogram is a unit of mass. It is a basic unit in a metric system, that is International System of Units (in abbreviated form SI).

From time to time the kilogram could 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. This definition was simply but hard to use.

Later, in 1889 the kilogram was defined by 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 IPK was in use until 2019, when it was replaced by another definition.

Today the definition of the kilogram is build 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 could be also divided to 100 decagrams and 1000 grams.

You know some information about kilogram, so now let's go to the pound. The pound is also a unit of mass. We want to emphasize that there are not only one kind of pound. What are we talking about? For example, there are also pound-force. In this article we are going to to centre only on pound-mass.

The pound is used in the British and United States customary systems of measurements. Naturally, this unit is used also in other systems. The symbol of the pound is lb or “.

There is no descriptive definition of the international avoirdupois pound. It is just equal 0.45359237 kilograms. One avoirdupois pound is divided to 16 avoirdupois ounces or 7000 grains.

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