Do you want to know **how much is 21 kg equal to lbs** and **how to convert 21 kg to lbs?** Here you go. In this article you will find everything about **kilogram to pound conversion** - theoretical and practical too. It is also needed/We also want to underline that whole this article is dedicated to a specific amount of kilograms - exactly one kilogram. So if you need to learn more about **21 kg to pound conversion** - keep reading.

Before we go to the more practical part - that is **21 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 we are starting.

We will begin with the kilogram. **The kilogram** is a unit of mass. It is a base unit in a metric system, in formal International System of Units (in abbreviated form SI).

Sometimes **the kilogram** could 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.

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 prepared of 90% platinum and 10 % iridium. The IPK was used 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 exactly 0.001 tonne. It is also divided to 100 decagrams and 1000 grams.

You learned something about kilogram, so now we can move on to the pound. The pound is also a unit of mass. It is needed to point out that there are more than one kind of pound. What are we talking about? For instance, there are also pound-force. In this article we are going to to concentrate only on pound-mass.

**The pound** is used in the British and United States customary systems of measurements. Of course, 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 exactly 0.45359237 kilograms. One avoirdupois pound is divided into 16 avoirdupois ounces and 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.”

Theoretical part is already behind us. In next section we will tell you **how much is 21 kg to lbs**. Now you know that 21 kg = x lbs. So it is time to get the answer. Let’s see:

**21 kilogram = 46.29707502 pounds.**

It is an accurate outcome of **how much 21 kg to pound**. It is possible to also round it off. After rounding off your outcome will be as following:
**21 kg = 46.2 lbs.**

You learned 21 kg is how many lbs, so see **how many kg 21 lbs**:
**21 pound = 0.45359237 kilograms.**

Of course, this time it is possible to also round off this result. After rounding off your outcome will be exactly:
**21 lb = 0.45 kgs.**

We are also going to show you **21 kg to how many pounds** and **21 pound how many kg** results in charts. Look:

We are going to begin with a chart for **how much is 21 kg equal to pound**.

Kilograms (kg) | Pounds (lb) | Pounds (lbs) (rounded off to two decimal places) |
