A peck is a unit of measurement for dry goods, such as grains or seeds. It is typically defined as 2 gallons (7.57 liters) in volume, but can also be expressed as 4 quarts (3.96 liters), 8 pints (4.11 liters), 16 cups (3.96 liters), or 32 half-pints (1.90 liters). The term comes from the Old English word "pic," meaning a small container, and was originally used to measure the volume of liquid goods such as wine or ale.
