Do you want to learn how much is 81.21 kg equal to lbs and how to convert 81.21 kg to lbs? Here it is. In this article you will find everything about kilogram to pound conversion - both theoretical and practical. It is also needed/We also want to emphasize that all this article is devoted to a specific number of kilograms - that is one kilogram. So if you need to learn more about 81.21 kg to pound conversion - keep reading.
Before we move on to the practice - that is 81.21 kg how much lbs conversion - we are going to tell you few theoretical information about these two units - kilograms and pounds. So we are starting.
We are going to start with the kilogram. The kilogram is a unit of mass. It is a basic unit in a metric system, known also as International System of Units (in abbreviated form SI).
Sometimes 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. This definition was simply but totally impractical to use.
Later, in 1889 the kilogram was described by the International Prototype of the Kilogram (in abbreviated 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 a new 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 equal 0.001 tonne. It is also divided to 100 decagrams and 1000 grams.
You know something about kilogram, so now let's go to the pound. The pound is also a unit of mass. We want to underline that there are more than one kind of pound. What does it mean? For instance, there are also pound-force. In this article we want to concentrate only on pound-mass.
The pound is in use in the British and United States customary systems of measurements. To be honest, this unit is used also in other systems. The symbol of the pound is lb or “.
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 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.”
