Milliliters to Liters Converter
1,000 milliliters = 1 liter.
Conversion result
Liters = milliliters ÷ 1000; milliliters = liters × 1000.
Primary source: NIST SP 811, Appendix B.8 conversion factors. Published SI table values may be rounded; this converter uses the exact underlying definitions. NIST Handbook 44, Appendix C supplies the underlying inch, pound and US liquid measure definitions. NIST SP 1038, footnote 19 defines the US cup, tablespoon and teaspoon in fluid ounces.
Worked example: 750 milliliters ÷ 1000 = 0.75 liter.
Common conversion values
The table follows the selected direction. Results display up to 12 significant digits; exact definitions are used before display rounding.
| milliliters | liters |
|---|---|
| 100 | 0.100 |
| 250 | 0.250 |
| 500 | 0.500 |
| 750 | 0.750 |
| 1000 | 1.000 |
The SI prefix milli means one thousandth. Thus 1 mL = 0.001 L exactly. Liter and litre are alternate spellings for the same unit; mL and L are the symbols.
Conversions use the measure named on the label. A US customary cup is 236.5882365 mL, rather than a 240 mL nutrition-label cup or a 250 mL metric cup. Actual measuring vessels and ingredient packing may vary.
