Answer:
A bushel is not a unit of length, rather it is a measure of dry volume, usually used in agriculture for the measurement of fruits, vegetables and grains. A bushel in the US measure is 2150.42 cubic inches, but is more typically measured in a bushel basket or box.
1 bushel =4 pecks = 8 dry gallons
On the commodity or trading markets, standard weights are now assigned to bushels of each individual item. For example: a bushel of soybeans is assigned the weight of 60 lbs, whereas a bushel of oats is 32 lbs. These standards may vary from market to market and from state to state, but each area has a standard.
