[3] [5] Use of the gal was deprecated by the standard ISO 80000-3:2006, now superseded. The gal is a derived unit, defined in terms of the centimeter–gram–second (CGS) base unit of length, the centimeter, and the second, which is the base unit of time in both the CGS and the modern SI system. In SI base units, 1 Gal is equal to 0.01 m/s 2.
Wine was measured with units based on the wine gallon of 231 cubic inches (3.785 L), while beer was measured with units based on an ale gallon of 282 cubic inches (4.621 L) and grain was measured with the Winchester measure, with a gallon of approximately 268.8 cubic inches (one eighth of a Winchester bushel or 4.405 L). In 1824, these units ...
The gallon is a unit of volume in British imperial units and United States customary units.. The imperial gallon (imp gal) is defined as 4.546 09 litres, and is or was used in the United Kingdom and its former colonies, including Ireland, Canada, Australia, New Zealand, India, South Africa, Malaysia and some Caribbean countries, while the US gallon (US gal) is defined as 231 cubic inches (3. ...
The U.S. uses the pre-1824 gallon (231 cubic inches, 3,790 cm 3) and Winchester bushel (2,150.42 cubic inches, 35,239.1 cm 3), as opposed to British 1824 definition of 1 imperial gallon (4.5 L; 1.2 US gal) = 10 lb (4.5 kg) of water and the bushel as 8 imperial gallons (36 L; 9.6 US gal).
[nb 1] (This was the basis for calling 64 gallons a quarter.) At some time before the 15th century, it was reduced to 252 gallons, so as to be evenly divisible by other small integers, including seven. [nb 2] Note that a 252-gallon tun of wine has a mass of approximately 2060 pounds, [6] between a short ton (2000 pounds) and a long ton (2240 ...

In the United States, the 42 US-gallon size as a unit of measure is largely confined to the oil industry, while different sizes of barrel are used in other industries. Nearly all other countries use the metric system. Thus, the 42 US-gallon oil barrel is a unit of measure rather than a physical container used to transport crude oil.
