Use as unit of weight
A table of weights from the secretaries of the different states, showing the number of pounds which their laws recognize as a bushel of different articles. c. 1854
Bushels are now most often used as units of mass or weight rather than of volume. The bushels in which grains are bought and sold on commodity markets or at local grain elevators, and for reports of grain production, are all units of weight. This is done by assigning a standard weight to each commodity that is to be measured in bushels. These bushels depend on the commodities being measured and the moisture content. Some of the more common ones are:
USA: 32 lb = 14.5150 kg
Canada: 34 lb = 15.4221 kg
Barley: 48 lb = 21.7724 kg
Malted barley: 34 lb = 15.4221 kg
Shelled maize (corn) at 15.5% moisture by weight: 56 lb = 25.4012 kg
Wheat at 13.5% moisture by weight and soybeans at 13% moisture by weight: 60 lb = 27.2155 kg
Other specific values are defined (and those definitions may vary within different jurisdictions, including from state to state in the United States) for other grains, oilseeds, fruits, vegetables, coal, hair, and many other commodities.
Government policy in the United States is to phase out units such as the bushel and replace them with metric mass equivalents.
The name "bushel" has also been used to translate non-US units of a similar size and sometimes shared origin, like the German "Scheffel".
