Understanding US Dry Quarts to Imperial Quarts Conversion
The US dry quart is a US customary dry-volume unit equal to 1.101221 litres, used for grains and produce. The imperial quart is the British measure of 1.136523 litres, one quarter of an imperial gallon. Because the two quarts are close in size, the conversion factor is near unity, making this a useful direct comparison between American dry and British imperial quart volumes.

What is the US Dry Quart?
The US dry quart is a unit of volume in the United States customary system used to measure dry commodities such as grains, berries, and produce. It is distinct from the (smaller) US liquid quart and belongs to the "dry measure" family built on the bushel.
Definition
The US dry quart is defined as one thirty-second of a US bushel, or equivalently 2 US dry pints, equal to exactly 67.200625 cubic inches.
Because the bushel is fixed at exactly 2150.42 cubic inches, the dry quart equals 2150.42 ÷ 32 = 67.200625 in³ = 1101.22094 cm³. It is about 16% larger than the US liquid quart (0.946353 L), so dry and liquid quarts must never be interchanged.
Origin and History
Dry measures descend from the English Winchester bushel, standardized in the 15th century and carried to colonial America. When the United Kingdom adopted the imperial system in 1824, the US retained the older Winchester standard, which is why US dry and imperial measures diverge to this day.
Law and Notable Facts
The US dry quart remains a legal customary unit, defined by the National Institute of Standards and Technology (NIST) via the international inch of 25.4 mm. In everyday US commerce, produce like berries is often sold in "dry pint" and "dry quart" containers, though these are nominal sizes rather than precisely enforced volumes.
Real-World Examples and Conversions
- A US dry quart of blueberries holds roughly 1.10 liters, or about 0.85 lb of fruit.
- 4 US dry quarts equal 1 US dry gallon (4.40488 L) and 8 dry quarts make 1 peck.
- Converting the other way, 1 liter equals about 0.9081 US dry quart.
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).
