A ton-force is one of various units of force defined as the weight of one ton due to standard gravity. [note 1] The precise definition depends on the definition of ...
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 tonne (/ t ʌ n / ⓘ or / t ɒ n /; symbol: t) is a unit of mass equal to 1,000 kilograms.It is a non-SI unit accepted for use with SI.It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton (United States customary units) and the long ton (British imperial units).
The water ton is used chiefly in Great Britain, in statistics dealing with petroleum products, and is defined as 224 imperial gallons (35.96 cu ft; 1.018 m 3), [22] the volume occupied by 1 long ton (2,240 lb; 1,016 kg) of water under the conditions that define the imperial gallon.

In engineering and physics, g c is a unit conversion factor used to convert mass to force or vice versa. [1] It is defined as = In unit systems where force is a derived unit, like in SI units, g c is equal to 1.
Units for other physical quantities are derived from this set as needed. In English Engineering Units, the pound-mass and the pound-force are distinct base units, and Newton's Second Law of Motion takes the form = where is the acceleration in ft/s 2 and g c = 32.174 lb·ft/(lbf·s 2).
A long ton, also called the weight ton (W/T), [1] imperial ton, or displacement ton, is equal to: 2,240 pounds (1,016.0 kilograms; 1.0160 metric tons) exactly 12% more than the 2,000 pounds of the North American short ton , being 20 long hundredweight (112 lb) rather than 20 short hundredweight (100 lb)
