What is the Imperial Gallon?
The imperial gallon is a unit of volume used in the United Kingdom and several Commonwealth countries, most commonly for measuring fuel, beverages, and other liquids. It is noticeably larger than the US gallon.
Definition
The imperial gallon is defined as exactly 4.54609 litres:
This is an exact defining relation, not an approximation. The imperial gallon is also subdivided into 4 quarts, 8 pints, or 160 imperial fluid ounces, and it is about 20% larger than the US liquid gallon (3.78541 L).
Origin and History
The gallon descends from medieval English measures for wine and ale, which historically had several conflicting definitions. The imperial gallon was standardised by the British Weights and Measures Act of 1824, originally defined as the volume of 10 pounds of distilled water weighed in air at 62 °F. In 1985 the UK redefined it in exact metric terms as 4.54609 litres, aligning the traditional unit with the SI system.
Law and Notable Facts
The imperial gallon remains a legally recognised unit in the UK and countries such as Canada, though metric litres are now standard for most trade. A key point of confusion is that the imperial gallon (4.54609 L) differs from the US liquid gallon (3.785411784 L); the two share a name but are distinct units, so fuel-economy figures quoted in "miles per gallon" are not directly comparable between the UK and the US.
Real-World Examples and Conversions
- A UK fuel purchase of 10 imperial gallons is about 45.46 litres.
- A car rated at 50 miles per imperial gallon achieves roughly 41.6 miles per US gallon for the same efficiency.
- 1 imperial gallon of fresh water weighs about 4.546 kg (roughly 10 pounds), reflecting its original 1824 definition.
- 1 imperial gallon equals about 1.20095 US gallons.
What is the Imperial Pint?
The Imperial pint is a unit of volume in the British imperial system, used mainly for measuring beverages such as beer, cider, and milk. It remains a familiar everyday measure in the United Kingdom and Ireland.
Definition
An Imperial pint is one-eighth of an Imperial gallon, or equivalently 20 Imperial fluid ounces. Since the Imperial gallon is defined as exactly 4.54609 litres, the pint follows directly:
That is, one Imperial pint equals exactly 4.54609 L ÷ 8 = 0.56826125 litres.
Origin and History
The pint descends from the Latin pincta (a painted mark on a vessel indicating a measure) and has existed in various local forms across medieval Europe. Britain standardised its liquid measures with the Weights and Measures Act of 1824, which defined the Imperial gallon and, with it, the modern Imperial pint. This replaced older wine, ale, and corn pints of differing sizes. It is notably larger than the US liquid pint of 473.176 mL.
Law and Notable Facts
The Imperial pint is a legally recognised unit in the United Kingdom, where draught beer and cider, and returnable milk containers, may still be sold by the pint despite general metrication. The UK "crown" pint stamp was long required on official pint glasses. Because it holds 20 fluid ounces versus the US pint's 16, an Imperial pint is about 20% larger than its American namesake.
Real-World Examples and Conversions
- A standard UK pint of beer contains 0.568261 litres, or about 568 mL.
- Doorstep milk in the UK is traditionally sold in one-pint (0.568 L) and two-pint (1.14 L) bottles.
- Two Imperial pints make one Imperial quart (1.13652 L), and eight pints make one Imperial gallon (4.54609 L).
- One Imperial pint equals roughly 1.20 US liquid pints (0.568261 L ÷ 0.473176 L).
