Before we go to the more practical part - it means 51 kg how much lbs calculation - we are going to tell you a little bit of theoretical information about these two units - kilograms and pounds. So let’s move on.

We are going to start with the kilogram. The kilogram is a unit of mass. It is a base unit in a metric system, known also 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.

First definition of a kilogram was formulated in 1795. The kilogram was defined as the mass of one liter of water. First definition was simply but difficult to use.

Then, in 1889 the kilogram was described using the International Prototype of the Kilogram (in short form IPK). The International Prototype of the Kilogram was made of 90% platinum and 10 % iridium. The IPK was in use until 2019, when it was switched by another 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 is also divided into 100 decagrams and 1000 grams.

There is no descriptive definition of the international avoirdupois pound. It is defined as exactly 0.45359237 kilograms. One avoirdupois pound could be divided into 16 avoirdupois ounces and 7000 grains.

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.”
