What You'll Learn
The UK imperial pint is 568ml
The UK imperial pint is 20% larger than the US pint, which is defined as 473ml. This difference in size is due to the two countries using different reference temperatures to define a fluid ounce in 1824, which led to diverging pint sizes over time.
The imperial pint is equal to one-eighth of an imperial gallon. In the UK, draught beer and cider must be sold in an imperial pint or a third of a pint, two-thirds of a pint, or multiples of half a pint.
The imperial pint is legally defined and standardised in the UK for several reasons. Firstly, it ensures fairness in trade, guaranteeing that customers receive a fair amount of beer for the price they pay. Secondly, it protects the cultural legacy of the pint glass, which is an iconic symbol of British drinking culture. Finally, it simplifies commerce, facilitating commercial activities such as taxing, pricing, and inspecting draught beer and cider sales.

The US pint is 473ml
The US pint is defined as one-eighth of a liquid gallon of precisely 231 cubic inches. This is different from the imperial pint, which is defined as one-eighth of an imperial gallon. The US liquid pint is also different from the less common US dry pint, which is defined as one sixty-fourth of a bushel and is approximately 551ml.
The US pint is equal to 16 US fluid ounces, while the UK imperial pint is equal to 20 fluid ounces. However, fluid ounces are not equal across the Atlantic. The British Imperial fluid ounce is equal to 28.413 milliliters, while the US Customary fluid ounce is 29.573ml.
The US pint is also smaller than the obsolete Scottish pint, or joug, which was equal to 1,696ml (2 pints 19.69 imperial fluid ounces).
The US pint of 473ml is used throughout the United States, but the term "pint" can refer to different volumes in other countries.

The UK pint is 20% larger than the US pint
The UK and the US have different measurement systems, which is why the UK pint is 20% larger than the US pint. The UK uses the British Imperial System, where a pint is 568.261 ml (20 fluid ounces). On the other hand, the US uses the US Customary System, where a pint is 473.176 ml (16 fluid ounces).
The British Imperial fluid ounce is equal to 28.413 milliliters, while the US Customary fluid ounce is 29.573 ml. This makes the US fluid ounce 4% larger than the Imperial one.
The Imperial pint is derived from the Imperial gallon, which was established in 1824 and is equal to the volume of 10 pounds of distilled water at a precise temperature of 16.667 °C (277.42 cubic inches). The Imperial pint is one-eighth of this volume, or about 568 ml.
The US Customary pint, on the other hand, is derived from the US Customary gallon, which is based on the British wine gallon of 231 cubic inches (3 inches x 7 inches x 11 inches). The US Customary pint is one-eighth of this volume, or about 473 ml.
The difference in pint sizes between the UK and the US can be attributed to the historical development of their respective measurement systems. While the US has used the US Customary System since its early days as a nation, the Imperial System was established later in 1824 for Great Britain and its colonies.
It's worth noting that almost all other countries have standardized on the metric system, and the term "pint" in these countries may refer to different volumes based on regional customs.

The imperial pint was established in 1824
The imperial pint is equal to 568 milliliters, or 20 fluid ounces, and is used in the United Kingdom, Ireland, and to some extent in Commonwealth nations. It is about 20% larger than the American pint. The imperial pint is part of the imperial system of measurement, which was once used in England and its colonies.
The establishment of the imperial pint in 1824 was significant as it standardised measurements across the British Empire. Prior to this, various gallons and pints were used, leading to inconsistencies and confusion. The imperial pint became the standard unit of measurement for beverages, ensuring that consumers received the correct amount each time.
The imperial pint continues to be widely used in the UK and Ireland, particularly in pubs and bars. It is also used in Commonwealth nations, although to a lesser extent, as some former colonies have converted to the metric system. The imperial pint remains an important unit of measurement for beverages, especially draught beer and cider, even as other measurements have transitioned to the metric system.

The pint is 1/8 of a gallon
In the UK, a pint of beer is 568ml or 20 fluid ounces. In the US, a pint of beer is 473ml or 16 fluid ounces. This is because the US pint is based on the older English measure of the wine gallon, while the UK adopted a new definition of the gallon in 1824.
The pint is a unit of volume or capacity in both the imperial and US customary measurement systems. It is used for liquids such as beer, milk, and fuel, as well as dry goods. In the US, the liquid pint is approximately 473ml, while the less common dry pint is 551ml.
The word "pint" comes from the Old French word "pinte" and may ultimately derive from the Vulgar Latin "pincta", meaning "painted". This may refer to the marks painted on the side of a container to indicate capacity.
In the UK, the pint is still used as a primary unit of measure for draught beer and cider, as well as milk in returnable containers. It can also be used as a supplementary unit in other contexts. For example, milk in plastic containers often comes in multiples of one pint, but must also display the metric equivalent.
