Litres, pints and gallons

Most of us know that a can of soft drink is 330 ml and a large bottle of milk holds 4 pints, but how do we change between these two quantities?

An understanding of this conversion is very valuable in everyday life, as in the UK we tend to use both imperial and metric measurements when we are talking about capacity.

You are expected to know that 1 litre is roughly 1.75 pints. You should also be aware that there are 8 pints in a gallon, which is equal to about 4.5 litres.
