| Definition | Result |

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).
What is the US Dry Gallon?
The US dry gallon (gal-dry) is a unit of volume used in the United States for measuring dry commodities such as grains, berries, and other agricultural produce. It is larger than the more familiar US liquid gallon.
Definition
The US dry gallon is defined as one-eighth of a US bushel, which equals 268.8025 cubic inches:
Exactly, 1 US dry gallon = 4.40488377086 liters. This is about 16.4% larger than the US liquid gallon (3.785411784 L) but slightly smaller than the imperial gallon (4.54609 L).
Origin and History
The dry gallon derives from the Winchester bushel, an English measure standardized in the late 17th century and defined as a cylinder 18.5 inches in diameter and 8 inches deep. The United States retained this bushel after independence, and the dry gallon is simply one-eighth of it. Dry measures existed because heaped commodities settle and compact differently than liquids, so a separate volume standard was practical for trade.
Law and Notable Facts
The US dry gallon is a legal US customary unit but is rarely used directly; dry commodities are more often traded in quarts, pecks, or bushels. It is not an SI unit. The UK abolished separate dry measures in 1824 when it adopted the imperial system, so the dry gallon is specifically an American measure.
Real-World Examples and Conversions
- 1 US dry gallon = 4.40488 L ≈ 268.8 cubic inches.
- 8 US dry gallons make 1 US bushel; 2 dry gallons make 1 peck.
- A US dry gallon holds about 4.6546 US dry quarts.
- 1 US dry gallon is roughly 1.164 US liquid gallons.
Frequently Asked Questions
How many US dry gallons are in an Imperial pint?
One Imperial pint equals 0.1290071 US dry gallons, because the pint (0.568261 L) is a small fraction of the 4.40488 L dry gallon.
Why convert a liquid pint into a dry gallon?
The comparison is useful when reconciling UK household liquid measures against US dry-goods capacities quoted in dry gallons.
How do I convert US dry gallons back to Imperial pints?
Multiply the number of US dry gallons by 7.751512 to recover Imperial pints.
Is the US dry gallon widely used?
It is uncommon in everyday retail but underpins US dry measures like the peck and bushel, appearing in agricultural contexts.
What is 8 Imperial pints in US dry gallons?
Multiply 8 by 0.1290071 to get 1.03206 US dry gallons.
