About these units

US Peck (pk)

US customaryTraditional unit (still used in some regions)

One quarter of a US bushel (8.81 L), a traditional measure for apples and other produce.

Anyone who has recited the tongue twister about Peter Piper has met the peck, a dry measure of a quarter bushel. The American version is about 8.81 L, or 8 dry quarts, and the imperial peck set after 1824 is larger at about 9.09 L. Scotland had its own pecks before that act, roughly 9 L for wheat, peas, beans and meal and about 13 L for barley, oats and malt, with four pecks making a firlot.

In Britain the peck is obsolete apart from the rhyme and a few older Bible translations, where it appears in Matthew 5:15. In the United States it lingers in grocery stores and farm stands, where apples and some other produce are still sold by the peck. NIST gives the US peck as 8.809768 L.

1 US peck = 8.809767542 liters (approximately).

Liter (L)

Metric (SI)Current unit

One cubic decimeter (1,000 cm³). The everyday metric unit of volume for drinks, fuel and cooking.

The liter was born in revolutionary France. In 1795 it was introduced as a republican unit and defined as one cubic decimeter, while the gram was tied to a cubic centimeter of water. The name comes from the older French litron, itself descended from a Byzantine Greek unit of weight, not volume. A small revision of the decimeter in 1798 left the first liter about 1.000974 of today's cubic decimeter, and in 1879 the international metric authorities adopted the liter with the symbol l.

The liter then took a strange detour. In 1901 it was redefined as the space taken up by one kilogram of pure water at its densest, which made it about 1.000028 cubic decimeters, and that muddled definition lasted until 1964, when it was restored to exactly one cubic decimeter. A capital L was added as an alternative symbol in 1979 because a lowercase l is easy to mistake for the digit 1, and NIST says L is the symbol to use in the United States. A liter of water is close to a kilogram, which is why a one-liter bottle feels like a kilo in the hand.

The liter is the reference unit for volume on this site.
