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).

Firkin (firkin)

Imperial (British)Traditional unit (still used in some regions)

9 imperial gallons (40.9 L), a quarter of a barrel. A traditional cask size for beer.

Probably from Middle English ferdekyn, which in turn likely comes from a Middle Dutch diminutive of vierde, fourth, the firkin is literally a little quarter: a quarter of a barrel. For beer in Britain that means 9 imperial gallons, about 41 liters (40.9 L here), or 72 imperial pints.

The word has been used for other goods too. A wine firkin was much bigger, at 70 imperial gallons by one reckoning, while British butter and cheese were sold by the firkin of 56 pounds, about 25 kilograms. An American dry firkin of 9 US gallons is only about 34 liters, and the word could also mean any small wooden tub for butter, lard or fish. Authors such as William Robinson in 1825 treated it as a recognised trade measure.

1 firkin = 40.91481 liters (exactly).
