# Convert cubic feet to gallon

Please provide values below to convert cubic foot [ft^3] to gallon (US) [gal (US)], or *vice versa*.

### Cubic foot

**Definition:** A cubic foot (symbol: ft^{3}) is a unit of volume in the Imperial and United States customary systems of measurement defined as the volume of a cube with side measurements of 1 ft × 1 ft × 1 ft. It is equal to 1,728 cubic inches, approximately 0.028317 cubic meters, and 28.317 liters.

**History/origin:** The cubic foot is derived from the foot, the definition of which is based on the international yard which was adopted in the 1950s and 1960s as exactly equal to 0.9144 m.

**Current use:** The cubic foot is used in the United States and in some parts of Canada and the United Kingdom, though in all of these countries, the SI (International System of Units) units of volume, liter, milliliter, and cubic meter, are also used.

### Gallon (US)

**Definition:** A gallon is a unit of volume specifically regarding liquid capacity in both the US customary and imperial systems of measurement. The US gallon is defined as 231 cubic inches (3.785 liters). In contrast, the imperial gallon, which is used in the United Kingdom, Canada, and some Caribbean nations, is defined as 4.54609 liters. In both systems, the gallon is divided into four quarts. Quarts are then divided into two pints and pints are divided into two cups. A cup is comprised of two gills, making one gallon equal four quarts, eight pints, sixteen cups, or thirty-two gills. Further differentiating the US and the imperial gallon, a US gill is divided into four fluid ounces, while an imperial gallon is divided into five. A US fluid ounce is therefore 1/128 of a US gallon while an imperial fluid ounce is 1/160 of an imperial gallon.

**History/origin:** The term gallon most closely originates from "galon" in Old Northern French and developed as a system for measuring wine and beer in England, resulting in measures such as the wine gallon, ale gallon, and imperial gallon.

**Current use:** In the United States (US), gallons are often used for larger containers, such as half gallon tubs of ice cream or one-gallon cartons of milk. Gallons are also widely used in fuel economy expression in the US, as well as some of its territories. The imperial gallon is used even more sparingly than the US gallon, with most countries around the world using liters when referencing fuel.
