Frequently asked questions
- How many milliliters are in a cup?
- It depends on the standard: a US legal cup is 240 mL, a metric cup is 250 mL, and a Japanese cup is 200 mL. Pick the one your recipe uses.
- How do I convert liters to gallons?
- One US gallon is about 3.785 liters. Type the liters, pick liters, and read the gallon row.
- Why are there different cup sizes?
- Countries define the cooking cup differently, and the gap compounds across a recipe, so this tool lets you pick the right one.
- Does my input get sent to a server?
- No. The conversion runs entirely in your browser; nothing you type leaves your device.
