Where this conversion shows up
The most treacherous kitchen conversion, because "cup" is not one size. The US customary cup is 236.6 mL, US nutrition labels use a 240 mL "legal" cup, and metric-country recipes mean 250 mL. This page converts the US customary cup — the one in American recipes.
Worked example
An American recipe wants 2 cups of milk: 2 × 236.588 = 473 mL. If you measured with a metric 250 mL cup instead you would pour 500 mL — about 6% too much, enough to loosen a batter noticeably.
Rounding and precision
For soups and sauces, rounding to 240 or even 250 mL per cup is harmless. For baking, where ratios rule, use 237 mL per US cup — or better, find the gram weights, since a "cup of flour" varies ±20% by how you scoop it.
