Short ton
Template:Short description The short ton (symbol STTemplate:Fact) is a measurement unit equal to Template:Convert. It is commonly used in the United States, where it is known simply as a ton,[1] although the term is ambiguous, the single word being variously used for short, long, and metric ton.
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).
United States
Template:Anchor In the United States, a short ton is usually known simply as a "ton",[1] without distinguishing it from the tonne (Template:Convert), known there as the "metric ton", or the long ton also known as the "imperial ton" (Template:Convert). There are, however, some U.S. applications where unspecified tons normally mean long tons (for example, naval ships)[3] or metric tons (world grain production figures).
Both the long and short ton are defined as 20 hundredweights, but a hundredweight is Template:Convert in the US system (short or net hundredweight) and Template:Convert in the imperial system (long or gross hundredweight).[1]
A short ton–force is Template:Convert.
