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 Fluid Ounce?
The imperial fluid ounce is a unit of volume in the British imperial system, used chiefly in the United Kingdom and Commonwealth countries for measuring liquids. It is slightly smaller than the US fluid ounce.
Definition
The imperial fluid ounce is defined as one one-hundred-sixtieth of an imperial gallon.
Since the imperial gallon is exactly 4.54609 litres, the imperial fluid ounce is exactly mL. There are 20 imperial fluid ounces in an imperial pint and 160 in an imperial gallon.
Origin and History
The fluid ounce descends from the medieval practice of relating volume to the weight of a substance—historically, one fluid ounce of water was intended to weigh about one avoirdupois ounce. The British imperial system was standardized by the Weights and Measures Act of 1824, which fixed the gallon as the volume occupied by 10 pounds of distilled water. The imperial gallon was later redefined in metric terms as exactly 4.54609 litres in 1985.
Law and Notable Facts
The imperial fluid ounce remains a legally recognized unit in the UK, though most packaged goods are now labeled in millilitres. Notably, the imperial fluid ounce (28.413 mL) is about 4% smaller than the US customary fluid ounce (29.574 mL), so an imperial pint (568 mL, 20 fl oz) is noticeably larger than a US pint (473 mL, 16 fl oz)—a frequent source of confusion for travelers.
Real-World Examples and Conversions
- A traditional British pint of beer is 20 imperial fluid ounces, or about 568 mL.
- A 5 imperial-fluid-ounce cup of tea equals roughly 142 mL.
- 10 imperial fluid ounces is exactly half an imperial pint, about 284 mL.
- Converting a US recipe: 8 US fluid ounces (236.6 mL) equals about 8.33 imperial fluid ounces.
