How to use Liters to Milliliters
Enter the value in L, then select Calculate. The result is shown in mL. Converts volume only. Converting a volume to mass also requires the substance density.
The formula
mL = L × 1,000
Examples
- 1 liters to milliliters
1,000 mL
- 10 liters to milliliters
10,000 mL
- 250 liters to milliliters
250,000 mL

Limitations and assumptions
Uses standard unit definitions. Results are rounded to at most eight decimal places; very small results may round to zero. Converts volume only. Converting a volume to mass also requires the substance density.
Frequently asked questions
How many milliliters are in one liter?
One liter equals 1,000 mL. The formula is mL = L × 1,000.
How do I convert liters to milliliters?
Use mL = L × 1,000. For example, 10 liters gives 10,000 mL. Enter your own value above and the converter does the arithmetic for you.
How do I convert milliliters back to liters?
Use the Milliliters to Liters converter, or invert the factor by dividing instead of multiplying.
Is this conversion exact?
Volume units differ by country: a US gallon is about 3.785 L while an imperial (UK) gallon is about 4.546 L, so check which system your recipe, label or fuel receipt uses.
