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!
