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).

Imperial Quart (qt (UK))

Imperial (British)Current unit

One quarter of an imperial gallon, 1.1365 L (40 imperial fluid ounces).

Quart comes from the Latin quartus, through French quart, and simply means a quarter: one quarter of a gallon. Because gallons of different sizes were in use over the centuries, quarts varied with them. The imperial version descends from the gallon fixed by the Weights and Measures Act 1824, defined by the weight of ten pounds of distilled water, which gave about 4.54 liters.

The modern figure is exact. The imperial gallon is now 4.54609 liters, so the imperial quart is 1.1365225 liters, equal to two imperial pints, eight gills or 40 imperial fluid ounces. British law still lists the quart as a quarter of a gallon among supplementary units. It is about 1.2 US liquid quarts, so recipes and cans from Britain, Canada and the United States can differ by a fifth. Canada's federal law even calls the imperial quart a pinte in French.

1 imperial quart = 1.1365225 liters (exactly).
