Quick and easy pounds to kilograms conversion
If you're just trying to convert pounds to kilograms for cooking or to know your own weight, there's a handy rule of thumb you can use:
To get kilograms, divide by 2 then take off 1/10th of your answer
Eg 100 pounds… Divide by two = 50 Kg. Take off 1/10th = (50 – 5) = 45 Kg.
This is close to the genuine answer of 45.35923kg, and is a much easier sum to do in your head!
Definitions of Pounds and Kilograms
The pound unit of weight is also known as the imperial pound, avoirdupois pound and international pound. The pound is defined as 453.59237 grams. Pound is often shortened to ‘lb’, so we can say 1lb=453.59237g
One kilogram (normally abbreviated to ‘Kg’) is almost exactly equal to the mass of one litre of water.
The kilogram is an SI base unit – this means that all other metric mass (weight) units are defined in terms of kilograms .
