Weights and measures are very confusing and that is largely due to
historical reasons. I think at one time even different counties within the
uk had different measures, they certainly kept their own "standards" and
until the coming of the railways had their own time.

There are certainly differences between the uk and the US. I believe they
kept hold of the measures the settlers took with them whereas the uk, in
standardising things, changed. I believe the US gallon is the same size as
what used to be known as "the Queen Anne gallon" in the uk.

Now what you probably need to know is that, in current uk measure:

there are 16 ounces weight (Avoirdupois - blame the French) to the pound
and one pound = 453.592g

There are 20 fluid ounces to the pint and a pint is 0.568 261 litre
 
Also "a pint of water weighs a pound and a quarter" (Standard rhyme which
used to be memorised by all school children) so 20 fluid ounces of water
(1 pint) weighs 16 ounces Av.

Hope this helps
