The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliliter is sometimes also referred to as a millilitre. Milliliters can be abbreviated as mL, and are also sometimes abbreviated as ml or mℓ. For example, 1 milliliter can be written as 1 mL, 1 ml, or 1 mℓ.

Since one milliliter is equivalent to one cubic centimeter, milliliters are sometimes expressed using the abbreviation for a cubic centimeter (cc) for things such as medical dosages or engine displacements.
