A bushel (abbreviation: bsh. or bu.) is an imperial and US customary unit of weight or mass based upon an earlier measure of dry capacity. The old bushel was equal to 2 kennings (obsolete), 4 pecks or 8 gallons and was used mostly for agricultural products such as wheat. In modern usage, the volume is nominal, with bushels denoting a mass defined for each commodity differently.
The name "bushel" is also used to translate similar units in other measurement systems.
The name comes from the Old French boissiel and buissiel, meaning "little box". It may further derive from Old French boise, thus meaning "little butt".
The bushel is an intermediate value between the pound and ton or tun that was introduced to England following the Norman Conquest. Norman statutes made the London bushel part of the legal measure of English wine, ale, and grains. The Assize of Bread and Ale credited to Henry III c. 1266 defined this bushel in terms of the wine gallon, while the c. 1300 Assize of Weights and Measures usually credited to Edward I or II defined the London bushel in terms of the larger corn gallon. In either case, the bushel was reckoned to contain 64 pounds of 12 ounces of 20 pence of 32 grains.
