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.
Facts about Liter
Definition: Liter (also spelled litre in British English) is a unit of volume with two official symbols in Latin: L and l. Liter is not part of the International System of Units (SI), however CGPM (the standards body which defines SI) accepts liter for use within SI. The SI units of volume are cubic decimeter (dm3), cubic centimeters (cm3) and cubic meters (m3). 1 liter equals = 1dm3 = 1000cm3 = 0.001m3
History: Liter was first introduced in 1795 in France as a new “republican units of measurement” that equaled one cubic decimeter. Liter (or litre) was named after litron, an old pre-revolutionary Carolingian measurement unit. 1 liter of water (liquid state) almost exactly equals 1 kilogram because in 1795 gram was defined 1 cubic centimeter of water at the melting ice temperature point. 3rd CGPM conference of 1901, a liter was defined as the space occupied by one kilogram of water at 3.98 °C (temperature of its maximum density) under 1 atmosphere pressure. In 1964 CGPM reverted to the previous and now current definition where 1 liter equals 1 decimeter (dm3).
Use: Liters are used to measure fluids (and occasionally solids that can be poured) by the size and capacity of their containers. The majority of fluid consumer commodities are measured in liters such as water, cooking oil, detergents, etc.
