What is the US Peck?
The US peck is a United States customary unit of dry volume, equal to a quarter of a bushel, used for measuring fruit, vegetables, and grain. It sits between the dry gallon and the bushel in the dry-measure system.
Definition
The US peck is defined as one quarter of a US bushel, or 8 US dry quarts, equal to exactly 537.605 cubic inches.
With the bushel fixed at 2150.42 in³, a peck equals 2150.42 ÷ 4 = 537.605 in³ = 8809.77 cm³. The US peck is about 3% smaller than the imperial peck (9.09218 L).
Origin and History
The peck is an old English dry measure, attested since the 14th century and long used for grain and produce. Its US form is tied to the Winchester bushel retained from colonial England, while the imperial peck follows Britain's 1824 reform.
Law and Notable Facts
The peck endures in the tongue-twister "Peter Piper picked a peck of pickled peppers" and in US orchard sales, where apples are still sold by the peck and half-peck. It remains a legal customary unit defined via the international inch.
Real-World Examples and Conversions
- A peck of apples weighs roughly 10–12 lb and fills about 8.81 liters.
- 1 US peck = 8 US dry quarts = 16 US dry pints = 8.80977 L.
- 4 US pecks make 1 US bushel; 1 liter ≈ 0.11351 US peck.
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).
