Length is the length (undefined), in feet; Beam is the beam, in feet. Depth is the depth of the hold, in feet below the main deck. The numerator yields the ship's volume expressed in cubic feet. 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.
Converting cubic tons (i.e., volumes) to measures of weight presents difficulties because organic materials such as timber vary in density. Approximate volume conversions, based on a timber cubic ton of 40 cubic feet: 1 ton (40 cubic feet) = 1.133 cubic metres; 1 cubic metre = 0.883 cubic tons (35.32 cubic feet)
Therefore the volume of hold space required for several tuns was greater than the total of the capacity of those tuns. 252 imperial gallons is just over 40 cubic feet (1.1 m 3). British practice by the 19th century was for a ton of cargo volume to be 50 cubic feet (1.4 m 3 ).
Gross tonnage is calculated by measuring a ship's volume (from keel to funnel, to the outside of the hull framing) and applying a mathematical formula. Gross tonnage (GT, G.T. or gt) is a measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. [1]
Defined in The International Convention on Tonnage Measurement of Ships that was adopted by the International Maritime Organization in 1969, the net tonnage replaced the earlier net register tonnage (NRT) which denoted the volume of the ship's revenue-earning spaces in "register tons", units of volume equal to 100 cubic feet (2.83 m 3).

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 m 3), [22] the volume occupied by 1 long ton ...
A shipping ton, freight ton, measurement ton or ocean ton is a measure of volume used for shipments of freight in large vehicles, trains or ships. In the USA, it is equivalent to 40 cubic feet (1.1 m 3) while in the UK it is 42 cubic feet (1.2 m 3). [1] [2] It should not be confused with other types of ton which also measure
Gross register tonnage (GRT, grt, g.r.t., gt), or gross registered tonnage, is a ship's total internal volume expressed in "register tons", each of which is equal to 100 cubic feet (2.83 m 3). Replaced by Gross Tonnage (GT), gross register tonnage uses the total permanently enclosed capacity of the vessel as its basis for volume. Typically this ...
