The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for 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.
