About these units

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).

Sextarius (sextarius)

Ancient RomanHistorical unit (no longer in standard use)Approximate value

One 48th of an amphora, about 0.55 L. The standard Roman liquid measure, a little under an imperial pint.

Literally a sixth, the sextarius was one sixth of a congius and one forty-eighth of an amphora quadrantal, which means one forty-eighth of a cubic Roman foot. It was the working core of Roman capacity measure, since both the liquid and the dry tables were built on it.

Its size is more contested than most. Wikipedia's text calculates about 540.3 mL from the cubic foot, its table gives 546 mL, which is the figure used here, and archaeological vessels fall between 500 and 580 mL, with no two surviving examples exactly alike. Wikipedia compares it to about 95 percent of an imperial pint, which is why it is often called a Roman pint. Smaller units were fractions of it, such as the cyathus at one twelfth, while the modius was 16 sextarii.

1 sextarius = 0.5458333333 liters (approximately).
