liters, gallons, cups, mL & more

Volume Unit Converter

Convert liters, milliliters, US and Imperial gallons, cups, pints, quarts and fluid ounces without hiding regional differences.

Try: 10 km to miles, 5′8″ to cm, or 7 lb 4 oz to kg.

How it works

Accurate conversion, with the context shown.

Volume labels matter: a US gallon is not an Imperial gallon, and fluid ounces are different from ounces by weight. This tool does not silently turn cooking volume into grams because the ingredient is required.

FAQ

Unit Converter FAQ

Is a US gallon the same as an Imperial gallon?

No. A US gallon is 3.785411784 liters; an Imperial gallon is 4.54609 liters.

Can I convert cups to grams?

Not directly. Volume cannot become weight without knowing the ingredient's density.

Why are fluid ounces labeled?

Fluid ounces measure volume, while ounces can also mean weight. The label prevents an ambiguous conversion.
