A recipe lists 0.75 L of milk, but my jug is marked in milliliters. What do I pour?

Pour 750 mL. Multiply 0.75 by 1000.

A tank holds 12 L. How many milliliters is that?

12 L is 12,000 mL. Multiply 12 by 1000.

Does 1 L equal 1000 cm³?

Yes. 1 L is 1 dm³, which is 1000 cm³, and 1 cm³ is 1 mL. So 1 L is 1000 mL.

Is 1 L exactly 1000 mL for every liquid?

Yes. Liters and milliliters measure volume, and the prefix milli means one thousandth. The mass of 1 L depends on the liquid, but the volume does not.

Formula

mL = L × 1000

Bottle labels, measuring jugs and lab glassware mix liters and milliliters, so a recipe in one unit often meets a container marked in the other. Multiply liters by 1000 to get milliliters. One liter is 1 cubic decimeter and one milliliter is 1 cubic centimeter, so 1 L is exactly 1000 mL. For US kitchen volumes, see cups to milliliters or the volume hub.
