History

At a certain time, the volume of the gallon depended on what was measured and at which place (country) measurement was made. However, at the 19th century, two definitions were of common use:

  • the gallon of Wine, whose value was of 231 cubic inches.
  • the gallon of ale of 282 cubic inches.

In 1824, the Great Britain adopted a measure close to the gallon of ale, and this measurement became the Imperial gallon. The Imperial gallon initially (in 1878) based on the volume of 10 books of Eau was distilled, weighed with the Pression of 30 inches of mercury and at a temperature of 62 °F (what gives approximately 277,41945 cubic inches).

The definition became metric in 1963.

During this time, the the United States had already standardized their measurement on the gallon of wine (“Queen Anne' S gallon”). The gallon was then defined like the volume of a Cylindre of 6 inches length by 7 inches in diameter, or 230,907 inches cubic. Nowadays, the American gallon is defined as being exactly 231 cubic inches.

The Imperial gallon is higher of approximately a fifth than the American gallon.

If the Imperial gallon and the American gallon are worth both 8 Pinte S, the US pint is divided into 16 liquid ounces US, whereas the imperial pint is worth 20 ounces liquid imperial; as follows:

  • one ounce liquid US is worth approximately 1,8047 cubic inches.
  • one ounce liquid imperial is worth approximately 1,7339 cubic inches.

One ounce liquid US constitutes a volume larger than the imperial ounce, whereas the American gallon is smaller than the Imperial gallon.
