This could contain a volume between 175 and 213 imperial gallons (210 and 256 US gal; 800 and 970 L), which could weigh around 2,000 pounds (910 kg) and occupy some 60 cubic feet (1.7 m3) of space.

[13] In the United Kingdom, Canada, Australia, and other areas that had used the imperial system, the tonne is the form of ton legal in trade.

It is used to determine the amount of money to be charged in loading, unloading, or carrying different sorts of cargo.

If it is lighter than salt water, e.g. feathers, freight is calculated in measurement tons of 40 cubic feet.

PC/UMS is based on a mathematical formula to calculate a vessel's total volume; a PC/UMS net ton is equivalent to 100 cubic feet of capacity.

[21] 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 m3),[22] the volume occupied by 1 long ton (2,240 lb; 1,016 kg) of water under the conditions that define the imperial gallon.

The large or dietary calorie (Cal) is equal to one kilocalorie (kcal), and is gradually being replaced by the latter correct term.

Early values for the explosive energy released by trinitrotoluene (TNT) ranged from 900 to 1100 calories per gram.

In order to standardise the use of the term TNT as a unit of energy, an arbitrary value was assigned based on 1,000 calories (1 kcal or 4.184 kJ) per gram.

Measurements in tons of TNT have been used primarily to express nuclear weapon yields, though they have also been used since in seismology as well.

The unit ton is used in refrigeration and air conditioning to measure the rate of heat absorption.
