Peck unit of measurement Britannica. WebIn 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.

In Scotland, the peck was used as a dry measure until the introduction of imperial units as a result of the Weights and Measures Act of 1824. The peck was equal to about 9 litres (1.98 Imp gal) (in the case of certain crops, such as wheat, peas, beans and meal) and about 13 litres (2.86 Imp gal) (in the case of barley, oats and malt). A firlot was equal to 4 pecks.
