Liters and cubic metric units
- 1 liter = 1,000 milliliters = 1,000 cubic centimeters.
- 1 milliliter is exactly the same volume as 1 cm³.
- 1 cubic meter = 1,000 liters; multiply m³ by 1,000 to get liters.
- 0.5 liter = 500 mL, while 250 mL = 0.25 liter.
Liters to gallons
The US liquid gallon is exactly 231 cubic inches, or 3.785411784 liters. Divide liters by 3.785411784 to get US gallons; 20 liters is about 5.283 US gallons.
The imperial gallon is exactly 4.54609 liters and must not be treated as the US unit. One imperial gallon is about 1.201 US gallons.
Volume conversion table
| Amount | Liters | US measure |
|---|---|---|
| 1 milliliter | 0.001 L | 0.033814 US fl oz |
| 1 US cup | 0.2365882365 L | 8 US fl oz |
| 1 liter | 1 L | 4.227 US cups |
| 1 US gallon | 3.785411784 L | 16 US cups |
| 1 cubic foot | 28.316846592 L | 7.481 US gal |
| 1 cubic meter | 1,000 L | 264.172 US gal |
Cups, ounces, pints, and quarts
A US gallon contains 4 quarts, 8 pints, 16 cups, or 128 US fluid ounces. Thus one US cup is exactly 8 US fluid ounces and 236.5882365 milliliters.
A fluid ounce measures volume; an ounce without the word fluid usually measures mass. Converting recipe quantities from mass to volume also requires ingredient density, which this unit converter does not assume.
Cubic feet and cubic dimensions
A cubic foot is the volume of a cube one foot on each side: exactly 1,728 cubic inches and 0.028316846592 cubic meters. A cubic yard contains 27 cubic feet.
If you have three dimensions rather than a volume, multiply length × width × height first, keeping every dimension in the same unit, then convert the resulting cubic unit.
