* The U.S. liquid gallon is abbreviated U.S. gal whereas the Imperial gallon is the Imp. gal. |

At one time, the volume of a gallon depended on what you were measuring, and where you were measuring it. But, by the [[19th century]], two definitions were in common use. The wine gallon, or "Queen Anne's gallon", which was 231 in³ (and became the legal basis for the U.S. fluid gallon), and the ale gallon, of 282 in³. |
|||

|||
In [[1824]], Britain adopted a close approximation to the ale gallon known as the Imperial gallon. The Imperial gallon was based on the volume of 10 [[pound|lb]] of distilled water weighed in air with brass weights with the barometer standing at 30 [[inch of mercury|in]] and at a temperature of 62[[Fahrenheit|°F]]. In [[1963]], this definition was refined as the space occupied by 10 [[pound|lb]] of distilled water of density 0.998 859 [[gram|g]]/[[millilitre|mL]] weighed in air of density 0.001 217 g/mL against weights of density 8.136 g/mL. This works out at approximately 277.419 45 in³. The metric definition of exactly 4.546 09 L was adopted shortly afterward. |
|||
The United States, by this time, had already standardised on the old wine gallon. It was at one time defined as the volume of a cylinder 6 in long and 7 in in diameter, or 230.907 in³. It had been redefined during the reign of [[Anne of Great Britain|Queen Anne]] as 231 in³ exactly, which remains the U.S. definition today. Thus 10 U.S. gallons equals approximately 8.327 Imperial gallons. The Imperial gallon is about a fifth larger than the U.S. gallon. |
|||
Both the Imperial and United States gallon are divided into 8 [[pint]]s. However in the US a pint is 16 fl oz whereas an Imperial pint is 20 fl oz. Thus a U.S. gallon is 128 fl oz and an Imperial gallon is 160 fl oz; this means that a US fluid ounce is around 1.8047 in³ and an Imperial fl oz is around 1.7339 in³. The US fluid ounce is actually bigger than the imperial, although the US gallon is smaller. |
|||
== History == |
|||
Until and before the 19th century there were even more gallons in use. |
|||
Examples: |
|||
; 224 in³ : standard wine gallon preserved at Guildhall |
|||
; 231 in³ : statute of 5th of Anne |
|||
; 264.8 in³ : ancient Rumford quart ([[1228]]) |
|||
; 265.5 in³ : Exchequer (Henry VII., [[1091]], with rim) |
|||
; 266.25 in³ : ancient Rumford ([[1228]]) |
|||
; 268.75 in³ : Winchester, statute 13 + 14 by William III. |
|||
; 271 in³ − 2 spoonfuls : Exchequer (Henry VII., [[1601]], ''E.E.'') |
|||
; 271 in³ : Exchequer ([[1601]], ''E.''), ''corn'' |
|||
; 272 in³ : corn ([[1688]]) |
|||
; 277.18 in³ : coal, statute 12 of Anne |
|||
; 278 in³ : Exchequer (Henry VII., with copper rim) |
|||
; 278.4 in³ : Exchequer ([[1601]] and [[1602]] pints) |
|||
; 280 in³ : Exchequer ([[1601]] quart) |
|||
; 282 in³ : Treasury (gallon for beer and ale) |

加侖（Gallon）是英美的容量單位，從前以計量用漢字寫作「嗧／𰇠（上「加」下「侖」）」；其同時是液體和乾量的容量單位，但兩者的容量略有不同（傳統英美度量衡的容量單位有分成“液量”和“乾量”兩類）。
