Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam. It is expressed in "tons burden " (Early Modern English: burthen ...
In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Although tonnage (volume) should not be confused with displacement (the actual mass of the vessel), the long ton (or imperial ton) of 2,240 lb is derived from the fact that a " tun " of wine typically weighed that much.
mass. Symbol. t Mg. In SI units: 1000 kg. The tonne (/ tʌn / ⓘ or / tɒn /; 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 ...
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 various tons are defined as units of mass. [ 2 ]
