Short ton

The short ton (abbreviation tn^[1]) is a measurement unit equal to 2,000 pounds (907.18 kg). It is commonly used in the United States, where it is known simply as a ton;^[1] however, the term is ambiguous, the single word "ton" being variously used for short, long, and metric tons.

The various tons are defined as units of mass.^[2] They are sometimes used as units of weight, the force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts a weight at one standard gravity of 2,000 pound-force (lbf).
