A bushel is a volume of measure and is equivalent to approximately 4 pecks (US) or 8 dry gallons (US).
Bushels are commonly used for units of mass or weight rather than of volume. Some of the more customary items where you will see bushels used to measure weight are:
- Oats: ~32 lbs.
- Barley: ~48 lbs.
- Malted barley: ~34 lbs.
- Corn: ~56 lbs.
- Wheat: ~60 lbs.
- Soybeans: ~60 lbs.
Fun Fact: Bushels have been in use since the 13th century to provide capacity measures in selling and trading (according to the Encyclopedia Britannica).
