Why do they use 'proof' instead of 'percent' in measuring alcohol strength?

I have also wondered about this so I researched it and came up with .... nothing :( It seems that companies do it because they have done it for a long time. In the UK, the proof is not twice the percentage as it is here in the US. It is a 7:4 ratio which makes things a little different. In the US it is required by law to put the percentage, but not the proof. Pointless for proofs I know, but what ya gonna do?
