Volume Converter
Convert volume among mL, L, m³ and US tsp, tbsp, fl oz, cup, pint, and gallon.
How to use
- Enter the volume and choose input/output units from metric L/mL/m³ or the available US liquid units.
Capabilities and scope
Liters provide the common reference for metric volume and common US recipe/liquid-volume units.
How it works
Every unit is normalized to liters. The implementation uses US liquid definitions such as 1 US gallon = 3.785411784 L and 1 US cup = 0.2365882365 L.
Example
1 US gallon is 3.785411784 L.
Useful for
- Convert recipe cups to milliliters
- Compare tank capacity in gallons and liters

Before you use it
- Cup, pint, and gallon values are US customary, not UK Imperial.
- Mass in grams cannot be converted to volume in mL without knowing material density.
