Volume Converter
Cooking and engineering recipes both insist on different volume units. This converts between metric (mL, L, m³) and US customary (fluid ounce, cup, pint, quart, gallon) plus the Imperial gallon used in the UK and Commonwealth. The UK gallon is ~20% larger than the US gallon, which is why recipes can go very wrong if you mix them up — the table below shows the difference at a glance. Runs entirely in your browser.
