Understanding Imperial Quarts to US Dry Gallons Conversion
The Imperial quart is a British liquid unit equal to one-quarter of an Imperial gallon, about 1.13652 litres. The US dry gallon is a customary unit for dry commodities equal to one-eighth of a US bushel, roughly 4.40488 litres. This conversion translates UK liquid quarts into the larger American dry-gallon measure used for grain and produce, letting you compare capacities across the two systems.

How to Convert Imperial Quarts to US Dry Gallons
Converting Imperial quarts to US dry gallons takes one multiplication by the fixed ratio.
- Take your Imperial quart value: Record the amount in imp-qt.
- Multiply by 0.2580142: Each Imperial quart equals 0.2580142 US dry gallons.
- State the result in gal-dry: The product is your dry-gallon figure.
- Worked result: For 25 imp-qt, compute 25 × 0.2580142 = 6.45036 gal-dry.

Which quart do you mean?
“quart” means different units by region. This page uses the Imperial quart (UK). 1 US Dry Gallons in each:
| Definition | Result |

| Imperial quart (UK) 1.137 L | 0.2580142 gal-dry (this page) |
What is the Imperial Quart?
The imperial quart is a unit of volume in the British imperial system, equal to one quarter of an imperial gallon. It is used in the United Kingdom and some Commonwealth countries for measuring liquids such as milk, beer, and oil.
Definition
An imperial quart is defined as exactly one quarter of an imperial gallon, or equivalently two imperial pints. Since the imperial gallon is exactly 4.54609 litres, the imperial quart follows directly:
Expressed exactly, one imperial quart equals 1.1365225 litres (1136.5225 mL), or 40 imperial fluid ounces.
Origin and History
The quart descends from the Latin quartus ("a fourth"), reflecting its status as a quarter of a gallon. Quarts existed in various English measures for centuries, but the modern imperial quart was fixed by the British Weights and Measures Act of 1824, which defined the imperial gallon and standardised the pint and quart that derive from it. This replaced the older, differing wine and ale gallons used previously.
Law and Notable Facts
The imperial quart remains a legal unit of measure in the United Kingdom, though metric units are now standard for most trade. It is notably larger than the US liquid quart: the imperial quart is about 1.1365 L while the US liquid quart is roughly 0.9464 L, making the imperial quart approximately 20% larger. This difference stems from the imperial and US systems adopting different gallon definitions.
Real-World Examples and Conversions
- One imperial quart of milk is about 1.137 litres, slightly more than a standard 1-litre carton.
- A recipe calling for 2 imperial quarts of stock needs roughly 2.273 litres.
- One imperial quart equals 40 imperial fluid ounces, versus 32 US fluid ounces in a US quart.
- Four imperial quarts make exactly one imperial gallon (4.54609 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 quart?
One Imperial quart equals 0.2580142 US dry gallons, since the quart (1.13652 L) is about a quarter of the 4.40488 L dry gallon.
How does a US dry gallon differ from a liquid gallon?
The US dry gallon (about 4.40488 L) is larger than the US liquid gallon (3.78541 L) because it is derived from the bushel rather than the wine gallon.
How do I convert US dry gallons back to Imperial quarts?
Multiply the number of US dry gallons by 3.875756 to return to Imperial quarts.
When is the dry gallon relevant?
It underpins US dry measures such as pecks and bushels and appears when produce or grain is quoted by dry volume.
What is 4 Imperial quarts in US dry gallons?
Multiply 4 by 0.2580142 to get 1.03206 US dry gallons.
