Magnums to Milliliters (magnum to mL)

1 magnum equals 1,500 milliliters exactly.

1 magnum = 1,500 milliliters

How to convert magnums to milliliters

To convert magnums to milliliters, multiply the number of magnums by 1,500. This factor is exact. To go the other way, multiply milliliters by 0.0006666666667 (rounded).

milliliters = magnums × 1,500

Example: 10 magnums = 15,000 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

Magnum (magnum)

Cooking & barCurrent unit

1.5 liters, two standard wine bottles.

Latin magnus, great, gives the magnum its name, a bottle holding 1.5 liters, exactly two standard 750 mL bottles. It is the smallest of the large formats in Wikipedia's table of wine bottle sizes and the one most often seen in ordinary shops and restaurants.

Wikipedia reports that most Champagne houses ferment only up to a magnum in the bottle, because bigger bottles are hard to riddle, and that larger formats are filled by transfer afterwards, which some believe lowers quality. The same article lists the magnum as the first step of a ladder of named sizes: double magnum at 3 L, Rehoboam at 4.5 L, Methuselah at 6 L. Its capacity is equivalent to about 50.7 US fluid ounces. Its date of first use is not given in the sources consulted here.

1 magnum = 1.5 liters (exactly).

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).
