A peck is an imperial and United States customary unit of dry volume,[1] equivalent to 2 dry gallons or 8 dry quarts or 16 dry pints. An imperial peck is equivalent to 9.09 liters and a US customary peck is equivalent to 8.81 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peck is no longer widely used, some produce, such as apples, are still often sold by the peck in the U.S. (although it is obsolete in the UK, found only in the old nursery rhyme "Peter Piper" and in the Bible – e.g., Matthew 5:15 in some older translations).
