===Effects of metrication===
[[File:2 pints of wholemilk.jpg|thumb|upright|Pints are commonly used for the sale of milk in the United Kingdom. The label gives both the metric and the imperial volume.]]
In the [[Metrication in the United Kingdom|British]] and [[Metrication in Ireland|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 [[Glass milk bottle|milk in returnable containers]].<ref>{{citation

</ref> 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.<ref>{{Cite web|title=Weights and Measures Act 1985|url=https://www.legislation.gov.uk/ukpga/1985/72}}</ref> Filtered milk and UHT milk sold in the UK is commonly sold in multiples of 1 litre bottles or containers.

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&nbsp;mL to 600&nbsp;mL, a conveniently rounded metric measure. Such milk bottles are no longer officially referred to as pints. However, the [[Beer in Australia#Beer glasses|"pint glass" in pubs in Australia]] remains closer to the standard imperial pint, at 570&nbsp;mL. It holds about 500&nbsp;mL of beer and about 70&nbsp;mL of froth, except in South Australia, where a pint is served in a 425&nbsp;mL glass and a 570&nbsp;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&nbsp;mL.<ref>[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</ref>

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&nbsp;mL).<ref>{{citation

A 375&nbsp;mL bottle of liquor in the US and the Canadian maritime provinces is sometimes referred to as a "pint" and a 200&nbsp;mL bottle is called a "half-pint", harking back to the days when liquor came in US pints, fifths, quarts, and half-gallons.<ref>{{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.

In France, a standard 250&nbsp;mL measure of beer is known as {{lang|fr|un demi}} ("a half"), originally meaning a half-pint.
