Wine Bottles to Milliliters (btl to mL)

1 wine bottle equals 750 milliliters exactly.

1 wine bottle = 750 milliliters

How to convert wine bottles to milliliters

To convert wine bottles to milliliters, multiply the number of wine bottles by 750. This factor is exact. To go the other way, multiply milliliters by 0.001333333333 (rounded).

milliliters = wine bottles × 750

Example: 10 wine bottles = 7,500 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

Wine Bottle (btl)

Cooking & barCurrent unit

The standard wine bottle holds 750 mL, about 25 US fluid ounces.

Standardisation of the 750 milliliter bottle is recent. Wikipedia does not explain why that figure was chosen, only that it has become the standard unit for wine sales. In the United States, bottles before 1979 followed the fifth, one fifth of a US gallon, about 757 mL. In 1979 the US adopted metric sizes for wine and spirits, making the basic bottle 750 mL as in Europe.

Larger formats are counted in multiples of this bottle: a magnum is two, a double magnum four and a Methuselah eight, while smaller ones include the half bottle of 375 mL and the 187.5 mL piccolo. A 750 mL bottle is exactly three quarters of a liter, roughly 25.4 US fluid ounces. Because the number is set by law for trade, a bottle sold today is the same size in Bordeaux, Napa or Sydney, whatever the shape of the glass.

1 wine bottle = 0.75 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).
