Facts about Gallon
In the United States customary units and imperial units, a gallon is a unit of volume. Nowadays 3 distinct versions are in use:
- The imperial gallon (imp gal), expressed as 4.54609 litres, which is or was used in Canada, Australia, 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 United States dry gallon “usdrygal” is expressed as 1/8 US bushel (exactly 4.40488377086 L).
There are four quarts in a gallon and eight pints in a gallon, which have different volumes in various systems. For both United States (liquid) and an imperial gallon, a symbol of the IEEE standard is gal.
The term most directly derives from galun, in Old Northern French – galon, but the usage was common in several languages, for instance, “jale” in Old French“ and gęllet” (means bowl) in Old English.
The gallon was created as the foundation of systems for measuring beer and wine in England. The sizes of gallons used in these two systems varied from each other. One was based on the wine gallon (equal in size to the US gallon) and the other one was either the ale gallon or the larger imperial gallon.
There were three definitions of the gallon in common use by the end of the 18th century:
- The corn gallon, or Winchester gallon, of about 268.8 cubic inches (approx. 4.405 L) – The corn or dry gallon is used (together with the dry quart and pint) in the United States for grain and various dry commodities.
- Queen Anne’s gallon or the wine gallon, which was 231 cubic inches (approx. 3.785 L) – The wine, fluid, or liquid gallon has been the standard US gallon since the early nineteenth century.
- The ale gallon of 282 cubic inches (approx. 4.622 L) – Britain adopted a close approximation, in 1824, to the ale gallon known as the imperial gallon and canceled all other gallons in favor of it.
Gallons are often used for larger containers In the US, such as one-gallon cartons of milk or half-gallon tubs of ice cream. In the United States, as well as some of its territories gallons are also widely used in fuel economy expression. The United States gallon is used more often than the imperial gallon. Most countries across the world use liters when referencing fuel.
Facts about Fluid Ounce
A fluid ounce (symbol: fl oz) is a unit of volume in the US customary and imperial systems of measurement. The United States fluid ounce is 1/16 of a US fluid pint, 1/128 of a United States liquid gallon, which equals 29.57 mL. The imperial fluid ounce is 1/20 of an imperial pint, and 1/160 of an imperial gallon, which equals 28.4 mL.
The fluid ounce was originally based on the volume occupied by one ounce (weight) of a given liquid like water or wine, accordingly varying based on the system being used. In 1824, the imperial gallon was represented as the volume of ten pounds of water at a temperature of 16.7°C. The definition of the imperial gallon was later changed to be equivalent to 4.54609 liters, which made the imperial fluid ounce equivalent to exactly 28.4130625 mL.
Originally, the US fluid ounce was based on the wine gallon used in England before 1824. In 1959 after the adoption of the international inch, the US fluid ounce became equal to exactly 29.5735295625 mL.
As the name shows, the fluid ounce is typically used as a measurement of liquid volume. It is mainly used in the United States and the United Kingdom as one of the many measurements of volume.
