The short ton (also known as net ton) equals to 2000 pounds and used in north america (united states and canada), the long ton (also known as weight or gross ton) is used in the imperial system (UK and some of the other english speaking countries) and defined as 2240 pounds or 1016 kilograms.
In the United States and formerly Canada a ton is defined to be 2,000 pounds (907 kg). Where confusion is possible, the 2240 lb ton is called  long ton  and the 2000 lb ton  short ton ; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.
