Peck

Peck, a measure of capacity for dry goods, such as grain, fruit, &c., used in Britain, and equivalent to two imperial gallons, or 554.548 cubic inches. It is thus the fourth part of a Bushel (q.v.). The old Scotch peck, the sixteenth part of a boll, when of wheat was slightly less than the imperial peck, but when of barley was equal to about 1.456 of it.
