There are 8 quarts in a peck. A peck is a measurement of dry volume, equal to 1/4 of a bushel and 16 pints. Two pecks make a kenning, and 4 pecks make a bushel.
A peck is a unit used in the U.S. customary and imperial systems of measurement. The word "peck" is of unknown origin, dating back to the late 13th century. Historically, this unit was used chiefly as a measure of oats for horses. Although not commonly used today, the unit is still used to measure produce. The peck is also the standard unit of weight for rocks and minerals.
