Volume is the category where the US and imperial systems diverge most damagingly. Gallons, quarts, pints and fluid ounces all exist in two sizes that differ by up to 20%, and nothing in the name warns you which one a figure uses. Recipes, fuel economy figures and container capacities all cross borders regularly, so it is worth checking which system a source is using before converting rather than after.

To go the other way, use milliliter = cup ÷ 0.00422675.
About these units
A millilitre is exactly one cubic centimetre. Because one millilitre of water weighs one gram, the unit doubles as a rough mass measure in the kitchen.
The US customary cup is 236.6 millilitres. A metric cup is 250 ml and an old imperial cup was 284 ml, so recipes rarely travel cleanly between regions.
Milliliter is also written millilitre, millilitres, milliliters and cc. Cup is also written cups.
