Hectoliters to Milliliters (hL to mL)

1 hectoliter equals 100,000 milliliters exactly.

1 hectoliter = 100,000 milliliters

How to convert hectoliters to milliliters

To convert hectoliters to milliliters, multiply the number of hectoliters by 100,000. This factor is exact. To go the other way, multiply milliliters by 0.00001.

milliliters = hectoliters × 100,000

Example: 10 hectoliters = 1,000,000 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

Hectoliter (hL)

Metric (SI)Current unit

100 liters. Used for wine, beer and milk production and for fishing quotas.

Large producers rarely count in single liters, so the hectoliter, 100 liters or 100 cubic decimeters, is the usual unit for beverage production and export figures. Milk, beer and wine statistics are quoted in it, and so are fishing catches and quotas. Since a cubic meter holds 1,000 liters, ten hectoliters make one cubic meter, and a hectoliter is one tenth of that larger SI volume.

Hecto- is the metric prefix for one hundred, giving the symbol hL. The unit is a practical middle step between the liter on a shop shelf and the cubic meter, and it avoids long strings of digits when production totals run to many thousands of liters. The figure used here is exactly 100 liters.

1 hectoliter = 100 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).
