Formula
milliliters = liters × 1000
Volume conversions use US customary measure (the cup, fluid ounce, and gallon are US definitions, not imperial). 1 US cup = 236.588 mL, 1 US gallon = 3.785411784 L.
About Liters and Milliliters
Liters (L): One cubic decimeter, or 1,000 cubic centimeters; one liter of water at standard conditions weighs almost exactly one kilogram, a coincidence that made the unit popular for everyday volume measurement. Common uses: Beverage container sizes, fuel (especially outside the US, where fuel is sold by the liter), engine displacements, and large-volume cooking and chemistry.
Milliliters (mL): One thousandth of a liter, where the liter is defined as one cubic decimeter; not strictly an SI unit (the SI volume unit is the cubic meter) but universal in cooking, medicine, and chemistry. Common uses: Liquid medication dosing, lab work, cooking (especially in metric countries), bartending, and any small-volume liquid measurement.
How the conversion works
Volume conversions use US customary measure (the cup, fluid ounce, and gallon are US definitions, not imperial). 1 US cup = 236.588 mL, 1 US gallon = 3.785411784 L.
The exact relationship is milliliters = liters × 1000, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between liters and milliliters comes up wherever volume measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
