About these units

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.

Omer (omer)

Biblical (Hebrew)Historical unit (no longer in standard use)Approximate value

A tenth of an ephah, about 2.2 L. The daily ration of manna in the Exodus account.

In Exodus 16 each Israelite is told to gather an omer of manna per person, which is the best known appearance of the word. It is sometimes translated as sheaf, and the same name was given to the first cut of the barley harvest offered at the Temple, from which the counting of the weeks to Shavuot takes its name. Elsewhere the unit is called the isaron, a tenth of an ephah.

Its size is disputed. The Jewish Study Bible is reported to give about 2.3 litres, close to the 2.2 litres used here, while the 1906 Jewish Encyclopedia is reported to give about 3.64 litres. Rabbinic tradition counts it as 43.2 eggs, and a flour omer is put at roughly 1.56 to 1.77 kg. The liquid equivalent is a tenth of a bath. In modern terms it is a little over a two litre soda bottle.

1 omer = 2.2 liters (approximately).
