What is the Pint?

The pint equals exactly one half of a US quart (0.473176473 liters) in the United States and 0.568261 liters in the United Kingdom (the imperial pint, 20% larger than the US pint). The British pint is iconic in pub culture — beer and cider are served in imperial pints in UK pubs, and the imperial pint glass is a regulated measure required by law. In the United States, milk is commonly sold by the pint (often as half-quart cartons), and ice cream containers are often pints (16 fl oz US). The pint relates to the gallon (8 pt = 1 gal), the quart (2 pt = 1 qt), the cup (2 cups = 1 US pt), and the fluid ounce (16 fl oz = 1 US pt; 20 fl oz = 1 imperial pt). The discrepancy between US and UK pints reflects the older 1824 imperial reform that the United States did not adopt.

What is the UK Gallon?

The UK imperial gallon equals exactly 4.54609 liters and is approximately 20% larger than the US gallon. Established by the British Weights and Measures Act of 1824 to standardize earlier ale and corn gallons, the imperial gallon was designed so that 10 pounds of pure water at 62°F occupied exactly 1 gallon. Although the United Kingdom has officially adopted the liter for fuel sales since 1995, the imperial gallon persists in everyday speech ('miles per gallon' for car fuel economy) and remains the standard unit in some Caribbean and Pacific Commonwealth countries. The imperial gallon relates to the US gallon (1 imp gal ≈ 1.201 US gal), the imperial quart (4 imp qt = 1 imp gal), the imperial pint (8 imp pt = 1 imp gal — the famous British pint of beer), and the liter (1 imp gal ≈ 4.546 L).
