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.
cups to liters formula
To go the other way, use cup = liter ÷ 0.23658824.
About these units
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.
A litre is exactly one cubic decimetre, or 1,000 cubic centimetres. One litre of water weighs almost exactly one kilogram, which is not a coincidence.
Cup is also written cups. Liter is also written litre, litres, liters and ltr.
