A peck is an imperial and United States customary unit of dry volume, equivalent to 2 gallons or 8 dry quarts or 16 dry pints (9.09 (UK) or 8.81 (US) liters). Two pecks make a kenning (obsolete), and four pecks make a bushel. Although the peck is no longer widely used, some produce, such as apples, is still often sold by the peck.
