The gallon is a unit of volume in British imperial units and United States customary units. Three different versions are in current use:

• the imperial gallon (imp gal), defined as 4.54609 litres, which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand, and some Caribbean countries;
• the US gallon (US gal), defined as 231 cubic inches (exactly 3.785411784 L), which is used in the United States and some Latin American and Caribbean countries; and
• the US dry gallon ("usdrygal"), defined as 1⁄8 US bushel (exactly 4.40488377086 L).

There are two pints in a quart and four quarts in a gallon. Different sizes of pints account for the different sizes of the imperial and US gallons.

The IEEE standard symbol for both US (liquid) and imperial gallon is gal, not to be confused with the gal (symbol: Gal), a CGS unit of acceleration.
