The British ton is the long ton, which is 2240 pounds, and the U.S. ton is the short ton which is 2000 pounds. Both tons are actually defined in the same way. 1 ton is equal to 20 hundredweight. It is just the definition of the hundredweight that differs between countries. In the U.S. there are 100 pounds in the hundredweight, and in Britain there are 112 pounds in the hundredweight.
