Before we get to the more practical part - that is 9.21 kg how much lbs calculation - we will tell you some theoretical information about these two units - kilograms and pounds. So we are starting.

## 9.21 kgs in pounds

We will begin with the kilogram. The kilogram is a unit of mass. It is a basic 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 this unit is kg.

Firstly, the definition of a kilogram was formulated in 1795. The kilogram was defined as the mass of one liter of water. First definition was not complicated but impractical to use.

Later, 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 replaced by another definition.

Nowadays the definition of the kilogram is based on physical constants, especially Planck constant. Here is the official definition: “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 equal 0.001 tonne. It is also divided into 100 decagrams and 1000 grams.

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

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

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