The metric ton is the name used for the tonne (1000 kg, 2 204.622 62 lb), which is about 1.6% less than the long ton. The US customary system also includes the kip, equivalent to 1,000 pounds of force, which is also occasionally used as a unit of weight of 1,000 pounds (usually in engineering contexts).
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).
This template is intended to allow entry of imperial weights (Avoirdupois), measured in tons, hundredweights, quarters and/or pounds (ton, cwt, qr and/or lb) and provide a conversion into pounds and into tonnes (metric tons) or kilograms (if the first parameter is blank or zero).
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)
The definition of units of weight above a pound differed between the customary and the imperial system - the imperial system employed the stone of 14 pounds, the hundredweight of 8 stone [Note 6] and the ton of 2240 pounds (20 hundredweight), while the customary system of units did not employ the stone but has a hundredweight of 100 pounds and ...
1 pound per square inch (psi) ≈ 6,895 Pa; Torque 1 pound-foot ≈ 1.356 N⋅m; Insulation 1 R-value (ft 2 ⋅°F⋅h/Btu) ≈ 0.1761 R SI (K⋅m 2 /W) Various combination units are in common use; these are straightforwardly defined based on the above basic units. Sizing systems are used for various items in commerce, several of which are U.S ...
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.
