Convert ml to gallon (2024)

Please provide values below to convert milliliter [mL] to gallon (US) [gal (US)], or vice versa.

Milliliter

Definition: A milliliter (symbol: mL) is a unit of volume that is accepted for use in the international system of units (SI). One milliliter is equal to 1 cubic centimeter (cm³), 1/1,000,000 cubic meters (m³), or 1/1000 liters.

History/Origin: The base unit of the milliliter is the liter (US spelling), spelled "litre" in SI terms. The term "litre" was originally part of the French metric system and was derived from the term "litron," one of the older versions of the French litre. Refer to the liter page for further details.

Current use: Milliliters are used to measure the volume of many types of smaller containers in everyday use, such as plastic bottles, cans, drinking, glasses, juice and milk cartons, yogurt, toothpaste tubes, perfume/cologne bottles, etc. Many measurement devices such as graduated cylinders, beakers, pipettes, measurement cups, etc. also use the measurement of milliliters.

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.
