Gallon Definition and Usage

The US liquid gallon is a unit of fluid volume equal to four quarts, eight pints, or sixteen cups.[1] The US liquid gallon should not be confused with the US dry gallon or the imperial gallon, which are different units of measure.

The gallon is a US customary unit of volume. Gallons can be abbreviated as gal, for example 1 gallon can be written as 1 gal.

Background and Origin

The gallon was originally used as the unit of fluid volume for measuring wine and ale in England. The gallon measurement used for wine was slightly different than that used for ale, and is equivalent to the US liquid gallon measurement in use today. This is the reason that sometimes the US liquid gallon is referred to as the wine gallon.
