A medium-sized apple weighs approximately 1/3 pound. One tree can produce up to 840 pounds of apples, which is equal to about 2,500 medium-sized apples.
One apple on record weighed roughly 3 pounds. At an apple orchard, apples are usually sold in pecks or bushels. A peck of apples is 10 to 12 pounds, or approximately 32 apples. A bushel is roughly 42 to 48 pounds, equal to about 126 apples. While that is a large amount of apples, it boils down to approximately 18 quarts of canned apples, which keep on the shelf for an extended period of time.
