Facts about Gallon

Basic Facts: The gallon is a unit of volume in the United States’ customary units and imperial units. 3 distinct versions are in current use:

– The imperial gallon [imp gal], defined as 4.54609 litres, which is or was used in Australia, Canada, the United Kingdom, Ireland, and some Caribbean countries;

– The US gallon [US gal] is defined as 231 cubic inches [exactly 3.785411784 L], which is used in the US and some Latin American and Caribbean countries;

– The US dry gallon “usdrygal” is defined as 1/8 US bushel [exactly 4.40488377086 L].

There are four quarts in a gallon and eight pints in a gallon, which have dissimilar volumes in different systems. For both US [liquid] and an imperial gallon, the IEEE standard symbol is gal.

History: The term most immediately comes from galun, in Old Northern French – galon, but the usage was common in several languages, for instance, “gęllet” [means bowl] in Old English and “jale” in Old French.

The gallon was formed as the base of systems for measuring wine and beer in England. The sizes of gallons used in these two systems differed from each other: 1) One was based on the wine gallon [equal in size to the US gallon], 2) The other one is either the ale gallon or the larger imperial gallon.

By the end of the 18th century, there were three definitions of the gallon in common use:

1. The corn gallon, or Winchester gallon, of about 268.8 cubic inches (≈ 4.405 L) – The corn or dry gallon is used [along with the dry quart and pint] in the US for grain and different dry commodities.

2. The wine gallon, or Queen Anne’s gallon, which was 231 cubic inches [49] (≈ 3.785 L) – The wine, fluid, or liquid gallon has been the standard US gallon since the early 19th century.

3. The ale gallon of 282 cubic inches (≈ 4.622 L). – Britain adopted a close approximation, in 1824, to the ale gallon known as the imperial gallon and abolished all other gallons in favor of it.

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

Use: In the United States, and to some extent in the United Kingdom the cubic inch and cubic foot are still used. However, SI [International System of Units] units of measurement such as the liter, milliliter, and cubic meter are also extensively used across these countries. In the United States, the aircraft and automotive industries use the cubic inch to some degree, however, SI accepted units of volume are also used.

For instance, in the United Kingdom, automotive model numbers are occasionally denoted in cubic inches.
