Liters to Milliliters
Convert liters (L) to milliliters (mL). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
milliliters = liters × 1000
liters = milliliters × 0.001
`
One liter is 1,000 milliliters, and one milliliter is 0.001 liters.
Conversion Table
| Liters | Milliliters |
|---|---|
| 1 L | 1,000 mL |
| 2 L | 2,000 mL |
| 5 L | 5,000 mL |
| 10 L | 10,000 mL |
| 25 L | 25,000 mL |
| 50 L | 50,000 mL |
| 100 L | 100,000 mL |
| 500 L | 500,000 mL |
| 1,000 L | 1,000,000 mL |
The Other Direction
| Milliliters | Liters |
|---|---|
| 1 mL | 0.001 L |
| 2 mL | 0.002 L |
| 5 mL | 0.005 L |
| 10 mL | 0.01 L |
| 25 mL | 0.025 L |
| 50 mL | 0.05 L |
| 100 mL | 0.1 L |
| 500 mL | 0.5 L |
| 1,000 mL | 1 L |
What Each Unit Is
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.
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.
A Sense of Scale
A large drink bottle is 2 L- A car fuel tank is 45–60 L
- A bath holds about 80 L
- A teaspoon is 5 mL
- An espresso is 30 mL
- A wine glass pour is 150 mL
Precision
The factor 1000 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 L with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 L becomes | Error |
|---|---|---|---|
| 0 | 1000 | 137,000 | — |
| 1 | 1000 | 137,000 | — |
| 2 | 1000 | 137,000 | — |
| 3 | 1000 | 137,000 | — |
| 4 | 1000 | 137,000 | — |
The right number of significant figures is set by your input, not by the converter. If you measured liters to three significant figures, the answer in milliliters is only good to three — writing more digits claims precision the measurement never had.
