The milliliter is one thousandth of a liter, identical to one cubic centimeter. Medicine doses, cosmetics, and recipe liquids are measured in milliliters.

Precision and Rounding: US and imperial volume units share names but differ in size (an imperial gallon is about 20% larger than a US gallon), so confirm which system a figure uses before converting. Kitchen work tolerates rounding to the nearest milliliter or quarter-teaspoon; fuel, chemistry, and brewing need three or more decimal places.
