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 4 pecks or 8 gallons and was used mostly for agricultural products such as wheat. Presently, the volume is usually only nominal, with bushels referring to standard quantities of mass instead.
