It was 20 hundredweights which equals 2240 pounds. The Yanks couldn't handle the arithmetic so call a ton 2000 pounds (everyone else calls that the "short ton", but not the yanks) Then we got the metric ton, which by some fortuitous coincidence is pretty close to the original ton. In international trade, people should be very careful to specify which ton they mean - UK, US or metric. --=20 Regards, Peter Wilkins
