But why? We had a perfectly good gallon and you had to go and ruin it! No wonder your petrol is so cheap!!Google search revealed;
In 1824 the British adapted the Imperial measure in which the gallon is based on 10 pounds or 277.42 cubic inches of water. The Americans had adopted a system where a gallon was comprised of 231 cubic inches of water. As a result, the U.S. gallon is 83.3 per cent of the Imperial gallon; put it another way, the Imperial gallon is about one-fifth or 20 per cent greater in volume than the American gallon.
