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 on the moisture content of the commodity. Some of the more common ones are:
* Oats:
** US: 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: 60 lb (27.2155 kg)
* Soybeans at 13% moisture by weight: 60 lb (27.2 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
