Short ton

The short ton is a unit of mass equal to 2000 lb (907.185 kg). In the United States it is often called simply "ton" without distinguishing it from the metric ton (or tonne) and the long ton —rather, the other two are specifically noted. There are, however, some U.S. applications for which "tons", even if unidentified, are usually long tons (e.g., Navy ships) or metric tons (e.g., world grain production figures).
