About the short ton
Wine casks lie behind every kind of ton. The word comes from tun, the term for the largest cask, and a tun of wine held roughly 2,000 pounds and took up about 60 cubic feet of cargo space. The short ton of 2,000 pounds keeps that round figure. It is used mainly in the United States and in some Canadian industries, while most of the world uses the tonne or, in the Commonwealth, the long ton.
The short ton is about 907 kg, roughly 10 percent less than a metric tonne, so the two should never be swapped when reading a statistic. The long and metric tons, by contrast, differ from each other by less than 2 percent. Weighing cargo on land is easy, but ships are traditionally described by displacement in long tons, so American shipping and naval documents can contain both kinds of ton at once. A freight bill may also use a measurement ton, which is a volume of 40 cubic feet. When writing for an international audience, spelling out short ton avoids confusion.
