is a unit of volume in majestic units and United States customary units. Three unlike versions are in current employ:

  • the regal gallon (imp gal), defined as

    4.54609 litres
    , which is or was used in the United Kingdom, Ireland, Canada, Commonwealth of australia, New Zealand, and some Caribbean countries;
  • the The states gallon (US gal), defined as

    784 L
    (231 cubic inches) which is used in the US and some Latin American and Caribbean countries; and
  • the US dry out gallon (“usdrygal”), defined as


    U.s.a. bushel (exactly

    86 L

At that place are two pints in a quart and four quarts in a gallon. Dissimilar sizes of pints account for the dissimilar sizes of the imperial and US gallons.

The IEEE standard symbol for both U.s.a. (liquid) and imperial gallon is
not to be confused with the gal (symbol: Gal), a CGS unit of acceleration.



The gallon currently has i definition in the imperial system, and two definitions (liquid and dry out) in the US customary organization. Historically, at that place were many definitions and redefinitions.

English language system gallons


There were a number of systems of liquid measurements in the United Kingdom prior to the 19th century.[iii]

  • Winchester or corn gallon was 272 in3
    (157 imp fl oz; 4,460 mL) (1697 Act 8 & 9 Will Iii c22)

    • Henry VII (Winchester) corn gallon from 1497 onwards was 154.80 imp fl oz (iv,398 mL)
    • Elizabeth I corn gallon from 1601 onwards was 155.70 imp fl oz (4,424 mL)
    • William Three corn gallon from 1697 onwards was 156.ninety imp fl oz (4,458 mL)
  • One-time English (Elizabethan) ale gallon was 282 in3
    (163 imp fl oz; iv,620 mL) (1700 Deed 11 Will 3 c15)
  • Old English (Queen Anne) wine gallon was standardized as 231 in3
    (133 imp fl oz; iii,790 mL) in the 1706 Act 5 Anne c27, only it differed before that:

    • London ‘Guildhall’ gallon (earlier 1688) was 129.19 imp fl oz (iii,671 mL)
    • Bailiwick of jersey gallon (from 1562 onwards) was 139.xx imp fl oz (three,955 mL)
    • Guernsey gallon (17th century origins till 1917) was 150.xiv imp fl oz (4,266 mL)
  • Irish gallon was 217 in3
    (125 imp fl oz; three,560 mL) (1495 Irish gaelic Act 10 Hen Seven c22 confirmed by 1736 Deed Geo Two c9)

Imperial gallon

The British majestic gallon is defined as exactly 4.54609 dmiii.[4]
Information technology is used in some Commonwealth countries, and until 1976 was defined equally the volume of 10 pounds (four.5359237 kg) of water at 62 degrees Fahrenheit (xvi.67 °C).[5]
There are iv quarts in a gallon, the imperial pint is defined as 0.56826125 litres (

gallon) and there are 20 imperial fluid ounces in an majestic pint,[4]
yielding 160 fluid ounces in an royal gallon.

US liquid gallon

The The states liquid gallon (oft called simply “gallon”) is legally defined as 231 cubic inches, which is exactly 3.785411784 litres.[7]
A Us liquid gallon tin can incorporate about iii.785 kilograms or 8.34 pounds of water at 3.98 °C (39.16 °F), and is about sixteen.7% less than the imperial gallon. There are four quarts in a gallon, two pints in a quart and 16 The states fluid ounces in a US pint, which makes the US fluid ounce equal to


of a Us gallon. In gild to overcome the furnishings of expansion and contraction with temperature when using a gallon to specify a quantity of material for purposes of trade, it is common to define the temperature at which the material will occupy the specified book. For instance, the volume of petroleum products[9]
and alcoholic beverages[10]
are both referenced to sixty °F (15.6 °C) in regime regulations.

Usa dry gallon


Since the dry measure out is 1-8th of a Usa
bushel of


cubic inches, it is equal to exactly 268.8025 cubic inches, which is

86 L
The US dry gallon is not used in commerce, and is also not listed in the relevant statute, which jumps from the dry pint to the bushel.[12]

Imperial gallon


Every bit of 2021, the imperial gallon continues to exist used as the standard petrol unit in four British Overseas Territories (Anguilla,[13]
the British Virgin Islands,[14]
the Cayman Islands,[15]
and Montserrat)[sixteen]
and 6 countries (Antigua and Barbuda,[18]
Commonwealth of dominica,[19]
Saint Christopher and Nevis,[22]
Saint Lucia,[23]
and Saint Vincent and the Grenadines).[24]

All ten of the countries and territories which use the imperial gallon every bit their petrol unit also use miles per hour for speed limits, and bulldoze on the left side of the route.

The United Arab Emirates ceased selling petrol by the imperial gallon in 2010 and switched to the litre, with Guyana following suit in 2013.[25]

Burma subsequently switched from the royal gallon to the litre in 2014.[28]

Popular:   Modele De Lettre Pour Etre Dans La Meme Classe

Antigua and Barbuda has proposed switching to selling petrol by litres since 2015.[29]

The gallon was removed from the list of legally divers primary units of measure catalogued in the European union directive 80/181/EEC for trading and official purposes, with effect from 31 December 1994. Under the directive the gallon could still exist used, just but as a supplementary or secondary unit.[30]
One of the furnishings of this directive was that the United Kingdom amended its own legislation to supersede the gallon with the litre as a primary unit of measure out in trade and in the carry of public business concern, effective from 30 September 1995.[31]
However inside the Great britain and Ireland, barrels and large containers of beer, oil and other fluids are sometimes marked in imperial gallons, as 50 litres is very close to 11 majestic gallons.

Ireland also passed legislation in response to the Eu directive, with the effective date beingness 31 Dec 1993.[34]
Though the gallon has ceased to exist a primary unit of trade, it can still exist legally used in both the UK and Ireland equally a supplementary unit.

Miles per regal gallon is used as the chief fuel economic system unit in the United Kingdom and as a supplementary unit in Canada on official documentation.[35]

In the Middle E, h2o-chiller bottles come up in multiples of the imperial gallon.

US liquid gallon


Other than the United States, petrol is sold by the US gallon in Belize, Colombia, Dominican Republic, Ecuador, Guatemala, Haiti, Honduras, Nicaragua, and Peru, likewise as in the Marshall Islands, Micronesia, and Palau, which are associated with the United States. Liberia, a onetime protectorate of the United States, uses US gallon when selling petrol.[38]

Despite its condition as a US territory, and dissimilar American Samoa,[39]
the Northern Mariana Islands,[xl]
and the Usa Virgin Islands,[42]
Puerto Rico ceased selling petrol past the United states gallon in 1980.[43]

Panama ceased selling petrol in U.s.a. gallons in 2013 and uses litres, while El Salvador followed suit in June 2021.[44]

In the Turks and Caicos Islands, both the US gallon and imperial gallon are used due to an increase in tax duties which was bearded past levying the aforementioned duty on the Usa gallon (iii.79 Fifty) as was previously levied on the Royal gallon (4.55 L).[45]

The Bahamas besides uses both the US gallon and imperial gallon.[46]

Relationship to other units


Both the U.s. liquid and majestic gallon are divided into four quarts (quarter gallons), which in turn are divided into two pints, which in turn are divided into two cups, (not in customary utilize exterior the United states), which in turn are farther divided into two gills. Thus, both gallons are equal to four quarts, eight pints, sixteen cups, or xxx-2 gills.

The imperial gill is further divided into 5 fluid ounces, whereas the US gill is divided into four fluid ounces, meaning an imperial fluid ounce is


of an imperial pint, or


of an royal gallon, while a United states of america fluid ounce is


of a US pint, or


of a US gallon. Thus, the imperial gallon, quart, pint, cup and gill are approximately 20% larger than their US counterparts, meaning these are not interchangeable, only the imperial fluid ounce is only approximately four% smaller than the US fluid ounce, pregnant these are often used interchangeably.

Historically, a mutual canteen size for liquor in the US was the “5th”, i.e. one-fifth of a United states gallon (or one-sixth of an imperial gallon). While spirit sales in the US were switched to metric measures in 1976, a 750 mL bottle is still sometimes known as a “fifth”.[48]



The term derives most immediately from
in Old Norman French,[50]
but the usage was common in several languages, for example


in Old French and


(bowl) in Onetime English. This suggests a common origin in Romance Latin, but the ultimate source of the word is unknown.[51]

The gallon originated every bit the base of operations of systems for measuring wine and beer in England. The sizes of gallon used in these two systems were different from each other: the first was based on the vino gallon (equal in size to the US gallon), and the second i either the ale gallon or the larger imperial gallon.

By the cease of the 18th century, at that place were 3 definitions of the gallon in common utilise:

  • The
    corn gallon, or
    Winchester gallon, of about
    268.viii cubic inches
    (≈ 4.405 Fifty),
  • The
    wine gallon, or
    Queen Anne’s gallon, which was
    231 cubic inches
    (≈ iii.785 L), and
  • The
    ale gallon
    282 cubic inches
    (≈ 4.622 L).

dry gallon
is used (along with the dry out quart and pint) in the United States for grain and other dry commodities. It is i-eighth of the (Winchester) bushel, originally divers as a cylindrical measure of


inches in diameter and 8 inches in depth, which made the dry gallon
8 in × (nine+


≈ 2150.42017 cubic inches. The bushel was afterward defined to be 2150.42 cubic inches exactly, thus making its gallon exactly

268.8025 inthree

86 50
); in previous centuries, there had been a corn gallon of betwixt 271 and 272 cubic inches.

fluid, or
liquid gallon
has been the standard US gallon since the early 19th century. The wine gallon, which some sources relate to the volume occupied past eight medieval merchant pounds of wine, was at one time defined as the volume of a cylinder 6 inches deep and seven inches in diameter, i.e.
half dozen in × (three+


≈ 230.907 06 cubic inches
. It was redefined during the reign of Queen Anne in 1706 as 231 cubic inches exactly, the earlier definition with
approximated to














{\displaystyle \pi r^{2}h\approx {\frac {22}{7}}\times \left({\frac {7}{2}}\correct)^{2}\times 6=231}

Although the wine gallon had been used for centuries for import duty purposes, in that location was no legal standard of it in the Exchequer, while a smaller gallon
(224 cu in)
was actually in apply, requiring this statute; it remains the United states of america definition today.

In 1824, U.k. adopted a close approximation to the
ale gallon
known as the
imperial gallon, and abolished all other gallons in favour of it. Inspired past the kilogram-litre human relationship, the imperial gallon was based on the volume of ten pounds of distilled water weighed in air with brass weights with the barometer standing at 30 inches of mercury and at a temperature of
62 °F.

In 1963, this definition was refined as the space occupied by 10 pounds of distilled h2o of density

0.998859 g/mL

weighed in air of density

0.001217 g/mL

against weights of density
viii.136 g/mL
(the original “brass” was refined equally the densities of brass alloys vary depending on metallurgical composition), which was calculated as

879 50

to x significant figures.[5]

The precise definition of exactly


cubic decimetres (also

4.54609 L
, ≈
277.419433 in3
) came after the litre was redefined in 1964. This was adopted before long afterwards in Canada, and adopted in 1976 in the Britain.[v]

Sizes of gallons


Historically, gallons of diverse sizes were used in many parts of Western Europe. In these localities, it has been replaced equally the unit of measurement of capacity past the litre.
