Peck
A peck is an imperial and United States customary unit of dry volume,[1] equivalent to 8 dry quarts or 16 dry pints. An imperial peck is equivalent to 9.09218 liters and a US customary peck is equivalent to 8.80976754172 liters. 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peck is no longer widely used, some produce, such as apples, are still often sold by the peck in the U.S. (although it is obsolete in the UK, found only in the old nursery rhyme "Peter Piper" and in the Bible – e.g., Matthew 5:15 in some older translations).
Scotland before 1824
[edit ]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 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.
