What is the US Bushel?
The US bushel is a large United States customary unit of dry volume used chiefly in agriculture to measure grain, fruit, and other bulk crops. It is the foundation of the US dry-measure system.
Definition
The US bushel (the Winchester bushel) is defined as exactly 2150.42 cubic inches.
This equals 2150.42 × 16.387064 cm³ = 35239.07 cm³. One bushel contains 4 pecks, 32 dry quarts, or 64 dry pints. It should not be confused with the imperial bushel (36.36872 L), which is about 3% larger.
Origin and History
The Winchester bushel dates to a 1696 English statute (with roots in medieval standards kept at Winchester) and was defined as a cylinder 18.5 inches in diameter and 8 inches deep, giving 2150.42 in³. The United States adopted this measure, while Great Britain replaced it with the imperial bushel in 1824.
Law and Notable Facts
Although volumetric by definition, US grain trading uses the bushel as a weight-based unit: legal "bushel weights" fix a bushel of wheat or soybeans at 60 pounds, corn and rye at 56 pounds, and oats at 32 pounds. Commodity exchanges quote grain prices per bushel on this weight basis.
Real-World Examples and Conversions
- A bushel of shelled corn weighs 56 lb (about 25.4 kg) and occupies roughly 35.24 liters of loose volume.
- 1 US bushel = 4 pecks = 8 US dry gallons = 35.2391 L.
- 1 US bushel ≈ 0.9689 imperial bushel; 1 cubic meter ≈ 28.38 US bushels.
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.
