pk

unit of capacity in the U.S. Customary and the British Imperial Systems of measurement. In the United States the peck is used only for dry measure and is equal to 8 dry quarts, or 537.6 cubic inches (8.810 litres). In Great Britain the peck may be used for either liquid or dry measure and is equal to 8 imperial quarts (2 imperial gallons), or one-fourth imperial bushel, or 554.84 cubic inches (9.092 litres). The peck has been in use since the early 14th century, when it was introduced as a measure for flour. The term referred to varying quantities, however, until the modern units were defined in the 19th century.
