Milliliters to Liters
Convert milliliters (mL) to liters (L). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
liters = milliliters × 0.001
milliliters = liters × 1000
`
One milliliter is 0.001 liters, and one liter is 1,000 milliliters.

| 1,000 L | 1,000,000 mL |
What Each Unit Is
Milliliters (mL) — one thousandth of a litre, equal to one cubic centimetre. The metric unit for small volumes; medicine and cooking both work in millilitres.
Liters (L) — exactly one cubic decimetre, or 0.001 cubic metres. A metric volume defined for trade; briefly redefined against the kilogram before reverting in 1964.
A Sense of Scale
A teaspoon is 5 mL- An espresso is 30 mL
- A wine glass pour is 150 mL
- A large drink bottle is 2 L
- A car fuel tank is 45–60 L
- A bath holds about 80 L
Precision
The factor 0.001 is exact by international agreement, not a rounded approximation. Any imprecision in a result comes from your input, not the conversion.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 mL with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 mL becomes | Error |
|---|---|---|---|
| 0 | 0 | 0 | 100.0000% |
| 1 | 0 | 0 | 100.0000% |
| 2 | 0 | 0 | 100.0000% |
| 3 | 0.001 | 0.137 | — |
| 4 | 0.001 | 0.137 | — |
The right number of significant figures is set by your input, not by the converter. If you measured milliliters to three significant figures, the answer in liters is only good to three — writing more digits claims precision the measurement never had.
