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. ...
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 cubic inch and the cubic foot are used as units of volume in the United States, although the common SI units of volume, the liter, milliliter, and cubic meter, are also used, especially in manufacturing and high technology. One cubic inch is exactly 16.387 064 mL. One cubic foot is equal to exactly 1,728 cubic inches (28.316846592 L), as 12 ...
The dry gallon's implicit value in the US system was originally one-eighth of the Winchester bushel, which was a cylindrical measure of 18.5 inches (469.9 mm) in diameter and 8 inches (203.2 mm) in depth, making it an irrational number of cubic inches; its value to seven significant digits was 268.8025 cubic inches (4.404884 litres), from an ...
[nb 3] The Queen Anne wine gallon of 231 cubic inches was adopted in 1707, and still serves as the definition of the US gallon. A US tun is thus the volume of a rectangular cuboid with dimensions 36 by 38.5 by 42 inches. When the imperial system was introduced the tun was redefined in the UK and colonies as 210 imperial gallons.
The cubic inch, cubic foot and cubic yard are commonly used for measuring volume. In addition, there is one group of units for measuring volumes of liquids (based on the wine gallon and subdivisions of the fluid ounce), and one for measuring volumes of dry material, each with their own names and sub-units.
One GGE of CNG pressurized at 2,400 psi (17 MPa) is 0.77 cubic feet (22 litres; 5.8 US gallons). This volume of CNG at 2,400 psi has the same energy content as one US gallon of gasoline (based on lower heating values: 148,144 BTU/cu ft (1,533.25 kWh/m 3) of CNG and 114,000 BTU/US gal (8.8 kWh/L) of gasoline.
