What this tool does
- Convert recipes and imported container labels: 1 US gallon in litres, 1 cup in millilitres.
- Estimate storage and shipping volume — 1 ft³ = 28.3168 L.
- Keep US and imperial gallons apart: they differ by about 20%, which matters for fuel, rentals and customs.

Frequently asked questions
How much bigger is an imperial gallon?
The US gallon is 3.785411784 L and the imperial gallon 4.54609 L — about 20.1% larger. Always check which one a recipe, rental or fuel figure uses.
Are cm³ and mL the same?
For conversion, yes: 1 cm³ = 1 mL. mL is used for liquids and cm³ for solids or imaging sizes.
How many cups are there?
At least three: the US legal cup (236.5882365 mL), a US customary cup close to it, and the metric 250 mL cup — plus the Japanese 200 mL cup. This tool uses the US legal cup.
Why do some numbers get very long?
Units span six orders of magnitude, so 1 m³ is 1,000,000 mL. Every value is printed with Number(value.toFixed(6)).
