If a "tun" is deemed to be equivalent to 100 cubic feet, then the tonnage is simply the number of such 100 cubic feet 'tun' units of volume. 100 the divisor is unitless, so tonnage would be expressed in 'ft 3 of tun'. [1] In 1678 Thames shipbuilders used a method assuming that a ship's burden would be 3/5 of its displacement.
Tonnage is a measure of the capacity of a ship, and is commonly used to assess fees on commercial shipping.The term derives from the taxation paid on tuns or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship.
Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
A short assay ton is approximately 29.17 g (1.029 oz) and a long assay ton is approximately 32.67 g (1.152 oz). [12] [citation needed] These amounts bear the same ratio to a milligram as a short or long ton bears to a troy ounce. Therefore, the number of milligrams of a particular metal found in a sample weighing one assay ton gives the number ...

TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
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).
George Moorsom ordered the entire fleet of British merchant ships to be measured according to the new System and then divided the total gross tonnage by the total registered tonnage. The result was 98.22 cubic feet (2.781 m 3 ) per gross ton, which was rounded to 100 cu ft (2.8 m 3 ) per ton.
