Unit Definition (bushel [US, dry])
The bushel [US, dry] is a traditional unit of volume used for measuring dry commodities such as grains and fruits. In the United States, the customary bushel is based on an old British unit known as the Winchester bushel. This unit dates to the early fourteenth century, at least: King Edward I defined the bushel to be 8 gallons in 1303. The form used in the U.S. was legalized by Parliament in 1696. One U.S. or Winchester bushel equals 4 pecks or 32 (dry) quarts; this is a volume of 2150.42 cubic inches or about 1.2445 cubic feet, and represents the volume of a cylindrical container 18.5 inches (47.0 cm) in diameter and 8 inches (20.3 cm) deep. The U. S. bushel holds about 35.239 07 liters. Traditionally, there is also a heaped bushel, which is 27.8% (sometimes 25%) larger than a regular bushel. The regular bushel is also called struck measure to indicate that the bushels have been struck, or leveled, rather then heaped. The origin of the word "bushel" is unclear; some scholars believe it derives from an ancient Celtic unit, but most believe it is of medieval French origin, probably a slang name for a wooden crate (the French word for wood is bois).
