In both of those systems, it is one-eighth of a gallon.

The British imperial pint is 20.095% larger than the US pint because the two systems are defined differently. Almost all other countries have standardized on the metric system, so although some of them still also have traditional units called pints (such as for beverages), the volume varies by regional custom.

The imperial pint (≈{{thinsp}}{{val|568|ul=mL}}) is used in Ireland, the United Kingdom, and other Commonwealth countries. In the United States, two kinds of pint are used: a liquid pint (≈{{thinsp}}{{val|473|u=mL}}) and a less common dry pint (≈{{thinsp}}{{val|551|u=mL}}).

Other former British colonies, such as Australia, South Africa and New Zealand, converted to the metric system in the 1960s and 1970s, so while the term {{em|pint}} may still be in common use in these countries, it may no longer refer to the British imperial pint once used throughout the British Empire.

{{anchor|Etymology}}Name

{{Further|wikt:pint#Etymology|label1=pint}}

Pint comes from the Old French word {{lang|fro|pinte}} and perhaps ultimately from Vulgar Latin {{lang|la|pincta}} meaning "painted", for marks painted on the side of a container to show capacity.{{cite web |url=http://www.merriam-webster.com/dictionary/pint |title=Pint |date=2013 |website=Merriam-Webster.com |access-date=31 May 2013}} It is linguistically related, though greatly diverging in meaning, to Pinto – an Italian, Spanish, and Portuguese name for a person with a speckled or dark complexion, often used as a surname in these languages.

In France, the French word {{lang|fr|pinte}} is now used to describe a half-litre, slightly smaller than an Imperial pint, but in Canadian French it is used to describe an Imperial quart and the French word {{lang|fr|chopine}} is used for an Imperial pint.{{cite news |url=https://www.lapresse.ca/actualites/sciences/2021-12-31/les-mysteres-des-mesures-de-l-alcool.php |title=Les mystères des mesures de l'alcool |newspaper=La Presse |date=31 December 2021 |last1=Perreault |first1=Mathieu }}

In the United States, traditional length and volume measures have been legally standardized for commerce by the international yard and pound agreement of 1959, using the definition of 1 yard as 0.9144 meters: from this definition, the metric equivalents for inches, feet, miles, area measures, and measures of volume are determined.

The liquid pint is legally defined as one-eighth of a gallon of exactly 231 cubic inches, i.e. 28.875 cubic inches or {{val|473.176473|u=mililitres}}.

The Scottish pint or {{lang|sco|joug}}, an obsolete Scottish unit, is equal to 1696 mL (2.93 Imperial pints). It remained in use until 1826, surviving significantly longer than most other old Scottish measurements.{{cite web |author= |date=2004 |title=Joug n. |url=http://www.dsl.ac.uk/entry/snd/joug |website=Scottish National Dictionary |location= |publisher= Dictionaries of the Scots Language |access-date=18 Apr 2025}}{{cite web |author= |date=n.d. |title=Pint, n., 2.a. |url=https://doi.org/10.1093/OED/9548784468 |website=Oxford English dictionary |location=Oxford |publisher= Oxford University Press |access-date=18 Apr 2025}}

The word pint is one of numerous false friends between English and French. They are not the same unit although they have the same linguistic origin. The French word {{lang|fr|pinte}} is etymologically related, but historically described a larger unit. The Royal pint ({{lang|fr|pinte du roi}}) was 48 French cubic inches (952.1 mL),{{cite book

In Canada, the Weights and Measures Act (R.S. 1985) defines a pint in English as one eighth of a gallon, but defines a {{lang|fr|pinte}} in French as one quarter of a gallon.{{Cite web|url=http://laws-lois.justice.gc.ca/PDF/W-6.pdf|title=Weights and Measures Act (R.S. 1985)}}{{efn|The site [http://www.ic.gc.ca/eic/site/mc-mc.nsf/eng/home Measurement Canada] contains a wealth of documentation on official Canadian measurements.

In Flanders, the word {{lang|nl|pintje}}, meaning 'little pint', refers only to a 250 mL glass of lager. Some West- and East-Flemish dialects use it as a word for beaker. The equivalent word in German, {{lang|de|Pintchen}}, refers to a glass of a third of a litre in Cologne and the Rhineland.

In South Australia, ordering "a pint of beer" results in 425 mL (15 fl oz) being served. Customers must specifically request "an Imperial pint of beer" to get 570 mL (20 fl oz). Australians from other states often contest the size of their beers in Adelaide.{{cite news |last=Keane |first=Daniel |date= September 8, 2017 |title=Getting to the bottom of the pint: the bitter problem of Adelaide's beer glasses |url= http://www.abc.net.au/news/2017-09-08/curious-adelaide-south-australia-beer-glass-sizes/8874960 |work= ABC News |location=Adelaide |access-date=September 9, 2017 }}

Equivalence

One US liquid pint of water weighs {{convert|1.0431756|lb|oz|4|lk=in}}, which gives rise to a popular saying: "A pint's a pound the world around".{{Cite web |title=A Pint's a Pound the World Around |url=https://govbooktalk.gpo.gov/2010/04/27/%e2%80%9ca-pint%e2%80%99s-a-pound-the-world-around%e2%80%9d/|department=Government Book Talk (blog) |publisher=U.S. Government Publishing Office |date=2010-04-27 |access-date=2017-01-30}}

However, the statement does not hold around the world, because the British imperial pint, which was also the standard measure in Britain's former colonies - such as Ireland, Canada, Australia, India, Malaysia, New Zealand and South Africa - weighs {{convert|1.2528|lb|oz|4|lk=in}}. This prompted the Society for the Diffusion of Useful Knowledge to coin a saying for use in Commonwealth countries: "a pint of pure water weighs a pound and a quarter".{{cite book|title=Penny Cyclopaedia of the Society for the Diffusion of Useful Knowledge|url=https://archive.org/details/bub_gb_NeFPAAAAMAAJ|year=1843|publisher=C.

History

The pint is traditionally one eighth of a gallon. In the Latin of the apothecaries' system, the symbol O ({{lang|la|cat=no|octarius}} or {{lang|la|cat=no|octavius}}; plural {{lang|la|octarii}} or {{lang|la|octavii}} – reflecting the "eighth" concept in its {{lang|la|cat=no|octa-}} syllable) was used for the pint.{{cite book |title=British Pharmacopoeia, 1864 |year=1916 |url=https://archive.org/stream/b20405558#page/n27/mode/2up/ | access-date=2016-09-22}} Because of the many historical definitions of a gallon, there have been many definitions of the pint.

Britain's North American colonies adopted the British wine gallon, defined in 1707 as exactly 231 cubic inches (3 in × 7 in × 11 in) as their basic liquid measure, from which the US wet pint is derived, and the British corn gallon ({{frac|1|8}} of a standard "Winchester" bushel of corn, or exactly 268.8025 cubic inches) as its dry measure, from which the US dry pint is derived.

In 1824, the British parliament replaced all the various gallons with a new imperial gallon based on ten pounds of distilled water at {{convert|62|F|1|abbr=on|lk=on}} (≈277.4194 cubic inches), from which the current imperial pint is derived.

The various Canadian provinces continued to use the wine gallon as a basis for their pint until 1873, well after Britain adopted the imperial system in 1824, while the traditional French {{lang|fr|pinte}} used in Lower Canada (Quebec) was twice the size of the traditional English pint used in Upper Canada (Ontario). After four of the British provinces united in the Canadian Confederation in 1867, Canada legally adopted the British imperial system of measure in 1873.{{citation

In 1873, the French Canadian {{lang|fr|pinte}} was defined as being one imperial quart or two imperial pints, while the imperial pint was legally called a {{lang|fr|chopine}} in French Canada. While the imperial pint, quart, and gallon are still legal units of measure in Canada, they are 20.095% larger than their American counterparts.

Historically, units called a pint (or the equivalent in the local language) were used across much of Europe, with values varying between countries from less than half a litre to over one litre. Within continental Europe, these pints were replaced with liquid measures based on the metric system during the 19th century. The term is still in limited use in parts of France and Central Europe, notably some areas of Germany[http://www.duden.de/rechtschreibung/Pint_Hohlmasz Duden], February 28, 2016. and Switzerland, where {{lang|de|ein Schoppen}} is colloquially used for half a litre. In Spanish holiday resorts frequented by British tourists, 'pint' is often taken to mean a beer glass (especially a dimple mug). Half-pint 285 mL, and pint mugs, 570 mL, may therefore be referred to as {{lang|es|media jarra}} ('half jar/jug') and {{lang|es|jarra (grande) }}('large jar/jug').{{citation needed|date=December 2021}}

=Effects of metrication=

File:2 pints of wholemilk.jpg

In the British and Irish metrication processes, the pint was replaced by metric units as the legally defined primary unit of measure for trading by volume or capacity, except for the sale of draught beer and cider, and milk in returnable containers.{{citation

As a supplementary unit, the pint can still be used in those countries in all circumstances. UK legislation mandates that draught beer and cider must be sold in one-third of a pint, two-thirds of a pint, or multiples of half a pint, which must be served in stamped, measured glasses or from government-stamped meters. Milk, in returnable containers, may come in pints without the metric equivalent stated. However, all other goods apart from the aforementioned exceptions must be sold or labelled in metric units. Milk in plastic containers mostly comes in multiples of 1 pint, but they are required to display the metric equivalent on packaging.{{Cite web|title=Weights and Measures Act 1985|url=https://www.legislation.gov.uk/ukpga/1985/72}} Filtered milk and UHT milk sold in the UK is commonly sold in multiples of 1 litre bottles or containers.

{{Cite web|title=Cravendale Semi skimmed Milk 2l|url=https://www.arlafoods.co.uk/products-overview/cravendale-semi-skimmed-milk-2l-550/}} Recipes published in the UK and Ireland would have given ingredient quantities in imperial, where the pint is used as a unit for larger liquid quantities, as well as the metric measure - though recipes written now are more likely to use metric units.The Baking Pocket Bible, Amy Lane, “Most UK recipes are now written in metric units but some recipes passed down through families or in older recipe books may be written using imperial measurements”.Skills in Food Technology, Jenny Ridgwell, “If you are using old recipe books to help with research for food ideas, you will find that the ingredients are given in Imperial measures.”

In Australia and New Zealand, a subtle change was made to 1 pint milk bottles during the conversion from imperial to metric in the 1970s: the height and diameter of the milk bottle remained unchanged, so that existing equipment for handling and storing the bottles was unaffected, but the shape was adjusted to increase the capacity from 568 mL to 600 mL, a conveniently rounded metric measure. Such milk bottles are no longer officially referred to as pints. However, the "pint glass" in pubs in Australia remains closer to the standard imperial pint, at 570 mL. It holds about 500 mL of beer and about 70 mL of froth, except in South Australia, where a pint is served in a 425 mL glass and a 570 mL glass is called an "imperial pint".

In New Zealand, there is no longer any legal requirement for beer to be served in standard measures: in pubs, the largest size of glass, which is referred to as a pint, varies, but usually contains 425 mL.[http://www.stuff.co.nz/dominion-post/news/local-papers/the-wellingtonian/7621775/Is-a-pint-really-a-pint-in-Wellington "Is a pint really a pint in Wellington?], 6 Sept 2012, The Dominion

After metrication in Canada, milk and other liquids in pre-packaged containers came in metric sizes so conversion issues could no longer arise. Draft beer in Canada, when advertised as a "pint", is legally required to be an imperial pint (568 mL).{{citation

A 375 mL bottle of liquor in the US and the Canadian maritime provinces is sometimes referred to as a "pint" and a 200 mL bottle is called a "half-pint", harking back to the days when liquor came in US pints, fifths, quarts, and half-gallons.{{cite book|publisher=Oxford University Press|title=Overcoming Alcohol Use Problems: A Cognitive-Behavioral Treatment Program|year=2009|url=https://archive.org/details/cognitivebehavio00epst|url-access=limited|author=Elizabeth E.
