About this tool
Convert volume between 11 units: liter, milliliter, cubic meter, cubic centimeter, cubic inch, cubic foot, US gallon, UK gallon, US quart, US pint and US cup. It is useful for recipes, fuel, aquariums and shipping. Conversions go through liters. US and UK gallons are listed separately because they differ: 3.78541 L vs 4.54609 L. Quarts, pints and cups are US units only; there are no imperial pint or fluid ounce options. Factors for the cubic units and the cup are rounded to about six digits, so results are accurate enough for everyday use. Results show up to 8 decimals.
How to use it
- Type the value to convert.
- Choose the From and To units.

- Fluid ounces are missing
- There is no fluid ounce option. One US cup is 8 US fluid ounces.
