How to convert Milliliters to Liters
1 mL equals 0.001 L. Use the converter above for any value, or read the table for common conversions.
L = mL × 0.001 · mL = L × 1000Multiply a milliliters figure by 0.001 to get liters, or divide it by 1,000 to go the other way.
Worked examples
- 1 mL= 0.001 L
- 2 mL= 0.002 L
- 5 mL= 0.005 L
- 10 mL= 0.01 L
- 20 mL= 0.02 L
What these units are
Milliliters (mL). A milliliter is one thousandth of a liter, and exactly the same volume as one cubic centimeter. It is used for drinks, medicine doses and recipe quantities.
Liters (L). A liter is one thousandth of a cubic meter. It is the everyday metric unit for liquids — bottled water, fuel, milk and cooking oil.
US and imperial units are kept separate because they are genuinely different sizes. Confirm which system a source means before trusting a converted figure.
Converting Milliliters to Liters in practice
Working in milliliters
A milliliter is one thousandth of a liter, exactly one cubic centimeter, or 0.000001 cubic meters. It is the small metric unit for liquid and dose volumes.
Medicine doses, laboratory samples, cosmetics, flavorings and small bottles of liquid are measured in milliliters. Syringes, measuring spoons and dosing cups are graduated in milliliters. Beverage cans and bottles often carry the volume on the label.
Milliliters to liters is a division by 1,000 exactly, and milliliters to cubic centimeters is a one-to-one identity. The fluid ounce is exactly 1/128 of a US gallon, and printed results are rounded, so a return conversion can differ in the final digit.
The mistake is treating a milliliter as a drop or a spoonful; a metric teaspoon holds five milliliters and a tablespoon fifteen. This site uses the US fluid ounce, not the imperial one, when converting small volumes.
Milliliters suit small quantities, liters suit bottles and fuel, and US cups and fluid ounces serve recipes written on the other scale. A 240-milliliter measure is the US legal cup, while a metric cup of 250 milliliters is a different unit.
Reading the result in liters
The liter is exactly one cubic decimeter, or 0.001 cubic meters, and it equals 1,000 milliliters. It is accepted for use with the International System as a named unit of volume.
Fuel, bottled water, cooking oil, paint, milk and engine coolant are sold in liters in most countries, and vehicles quote fuel use in liters per 100 kilometers. Recipes use the unit as well.
A liter is exactly 0.001 cubic meters by definition, so the liter to milliliter and liter to cubic meter conversions are exact. Rounded display means a liter value converted to gallons and back may not return identically.
The judgement call is which gallon: this site uses the US gallon of exactly 3.785411784 liters, not the imperial gallon of 4.54609 liters. Mixing the two understates or overstates a fuel or water volume by roughly twenty percent.
Liters and milliliters differ by a thousand and share the metric scale, while the US gallon is a separate unit near 3.79 liters. Fuel and drinks are sold in those measures, so a metric recipe written in US cups or fluid ounces needs converting first.
Checking a milliliters to liters conversion
The metric volume units are a clean decimal chain around the liter, so liters to milliliters is a shift of three places and cubic meters to liters is a shift of three the other way. Those pairs a reader can do without a converter.
Every pair that names a US or imperial liquid unit has to go through the definition first, because three of these units differ from a metric unit by amounts too large to round away: a liter is not a quart, a gallon is 3.785411784 liters in the US system and 4.54609 in the imperial one, and a US fluid ounce is not an imperial fluid ounce.
When checking a volume conversion, convert into liters and out again, or measure the container. The mistake that survives every other check is reading a US measure as the imperial unit of the same name, which changes a recipe, a fuel figure or a tank size by about a fifth.
