The average weight of an apple is 1/3 pound, or approximately 5 ounces, according to the Apple Journal of the Kitchen Reference Guide. Weight varies by the type and size of apple.
The United States grows over 2,500 varieties of apples, with some as small as the size of a cherry and others as large as a grapefruit. The largest apple on record weighs 3 pounds.
Two pounds of apples are required to make a 9-inch apple pie. The average apple tree yields over 800 pounds of apples during a harvest, and the average U.S. consumer eats over 40 pounds of apples each year.
