Although sizes and weights vary a great deal, an average ear of corn weighs between 1 and 1.5 pounds. This estimate is based on how many dry ears of corn it takes to complete a bushel of corn.
The USDA uses a bushel as its official measuring unit for corn. A bushel of corn is 56 pounds. Using the standard dry-moisture rate of 15.5 percent, it takes roughly 70.7 ears of dry corn to produce one bushel. Therefore, the ideal weight of one ear of corn is 1.26 pounds. The USDA estimates that 158.8 bushels of corn is produced for every acre of crop planted. This equates to roughly 11,227 ears of corn (14,146.02 pounds) produced per acre.
