Pounds and kilograms are both units for measuring mass. Pound refers to an imperial system of measuring weight or mass. Kilogram, on the other hand, was adopted under the SI or International System of Units in 1959.

However, there are incremental differences when calculating mass in kilograms as opposed to the same calculation in pounds. How many kg in one pound is a common query for many individuals trying to compound the mass of an object from kilogram to pounds, or vice versa.

One Pound is Equal to How Many Kg

One pound is equal to just under half a kilogram. To be exact,

1 pound = 0.453 kg

By this same equation, one can derive how many pounds in a kilogram.

1 kg = 2.204 pounds

Before proceeding to learn the difference between pound and kg, let us understand a bit more about kilogram and pound.

What is Kilogram?

Under the SI system of measurement, a kilogram is considered equal to the mass of one litre of water. Stored in a vault at the International Bureau of Weights and Measures, France, IPK is a standard Iridium-Platinum cylindrical figure that is exactly equal to 1 kg. To understand the relation between pound and kg, you should also learn more about a pound.

What is Pound?

A pound is one of the units of measuring mass under the Imperial system. Other scales include stone and ounce. Abbreviated as ‘lb’ due to the pound’s association with the Roman Libra, this unit has several varieties in different countries.

The exact answer to how many kg in one pound is 0.45359237 kg. Nonetheless, remembering this figure is difficult, which is why most calculations consider 1 pound = 0.450 kg.

Pounds to Kilogram Formula

Being able to answer how many kg in one pound is not sufficient. You should also be able to convert pounds into kilograms quickly, as well. To do so, simply multiply the mass in kg with 0.453. For example, 3 pounds will be equal to 3 x 0.453 kg.

Kilogram to Pounds Formula

In a similar fashion, when converting mass from kilogram to pounds, multiply the weight in kg with 2.204.

Now that you know the difference between kg and pound, here is a quick exercise to solve.

Exercise – 1

Q. Shruti orders 45 pounds of cement for the construction of her home. However, she receives only 13 kg of cement. How many pounds of cement does she need to complete her order?

Solution:

Method 1

Start by converting 45 pounds into kg.

Thus, cement ordered (in kg) = 45 x 0.453 = 20.38kg

Shruti received 13 kg of cement from her order. Thus, cement still to be delivered is (20.41 - 13) kg. Therefore, she is yet to receive 7.38 kg of cement.

Pounds of cement yet to be delivered = 7.38 x 2.20 = 16.236 pounds.

Method 2

This is the faster procedure, involving just one conversion.

Start by converting 13 kg into pounds.

Cement delivered = 13 x 2.204 = 28.65 pounds.

Cement to be delivered = 45-28.65 = 16.35 pounds

The calculation becomes extremely simple when one can remember the lbs to kilos formula.
