Which fluid ounce do you mean?
“fluid ounce” means different units by region. This page uses the Imperial fluid ounce (UK). 1 US Dry Pints in each:
| Definition | Result |
|---|---|
| US fluid ounce 29.57 mL | 0.05371044 pnt-dry |
| Imperial fluid ounce (UK) 28.41 mL | 0.05160284 pnt-dry (this page) |
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.
What is the US Dry Pint?
The US dry pint is a United States customary unit of volume for dry goods such as fruit, grain, and vegetables. It is larger than the US liquid pint and is part of the bushel-based dry measure system.
Definition
The US dry pint is defined as one half of a US dry quart, equal to exactly 33.6003125 cubic inches.
Since the US bushel is exactly 2150.42 in³, a dry pint equals 2150.42 ÷ 64 = 33.6003125 in³ = 550.610471 cm³. This is roughly 16% larger than the US liquid pint (0.473176 L).
Origin and History
Like all US dry measures, the dry pint derives from the English Winchester bushel used in colonial America. The US kept this pre-1824 standard while Britain moved to the imperial system, producing the lasting split between US and imperial pints.
Law and Notable Facts
The dry pint is a recognized US customary unit defined through the international inch. It survives most visibly at grocery stores and farmers' markets, where berries and cherry tomatoes are commonly sold by the "pint" basket, a nominal dry-pint container.
Real-World Examples and Conversions
- A dry pint of blueberries holds about 0.55 liter, typically around 12 oz of fruit by weight.
- 2 US dry pints equal 1 US dry quart (1.10122 L).
- 1 liter equals about 1.8162 US dry pints.
