Omers to Milliliters (omer to mL)

1 omer equals 2,200 milliliters exactly.

1 omer = 2,200 milliliters

How to convert omers to milliliters

To convert omers to milliliters, multiply the number of omers by 2,200. This factor is exact. To go the other way, multiply milliliters by 0.0004545454545 (rounded).

milliliters = omers × 2,200

Example: 10 omers = 22,000 milliliters.

Pints, quarts, gallons and fluid ounces differ between the US and the UK. Units are labeled 'US' or 'imperial' to avoid confusion.

About these units

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).

Milliliter (mL)

Metric (SI)Current unit

One thousandth of a liter, or exactly 1 cubic centimeter. Used for medicine, cooking and small containers.

Milliliters inherit everything from the liter, since the prefix simply means one thousandth. Because the liter is a cubic decimeter, a milliliter works out to exactly one cubic centimeter, a coincidence the metric system built in on purpose so that volume, length and mass interlock. One milliliter of water has a mass of about one gram, so a dosing syringe, a kitchen scale and a measuring jug can all be checked against one another.

Today milliliters dominate wherever small amounts must be measured precisely: medicine, flavorings, perfume, shampoo and the fine print on drink labels. Spelling is a mild regional split, with uppercase mL preferred in the United States, Canada and Australia and lowercase ml common in the UK and Europe. For scale, a US teaspoon is just under 5 mL, a US tablespoon is about 14.8 mL, and the US nutrition-label cup is exactly 240 mL, so one such cup is 240 of these tiny units.

1 milliliter = 0.001 liters (exactly).
