How it works
US cup = Milliliter × 0.004226753. Every value is converted through a single liter base unit using internationally defined conversion factors, so any from/to pair stays consistent.
Good to know
Converting milliliters to US cups is something home cooks reach for constantly when following a recipe written for the wrong region. European, British, and Australian recipes routinely list ingredients in milliliters, while American recipes lean on cups — so anyone baking a French cake or stirring a US smoothie bowl ends up bridging the two. It comes up most with liquids like milk, water, broth, and oil, where pouring an accurate volume actually changes how the dish turns out.
The mismatch exists because the two units belong to different systems. The milliliter is a metric unit (one-thousandth of a liter), defined cleanly and used almost everywhere outside the United States. The US customary cup, by contrast, is a legacy imperial-style measure pinned to 236.5882 mL. That awkward number is exactly why a converter is handy — there's nothing intuitive about it.
For a fast mental shortcut, remember that a US cup is very close to 237 mL, so roughly 240 mL is about one cup. Cutting it the other way, every 250 mL (a common metric "metric cup") is a touch over one US cup — about 1.06 cups. So when you see a 250 mL measure on a carton, just treat it as one generous cup and you'll rarely be off in everyday cooking.
The biggest trap is assuming all cups are equal. The US cup is 236.59 mL, the metric cup is 250 mL, and the older UK imperial cup is about 284 mL — using the wrong one can throw a recipe off by 20% or more. This converter uses the US cup. Also keep in mind that cups measure volume, not weight, so 240 mL of honey and 240 mL of water fill the same cup but weigh very differently.

How many milliliters are in a US cup?
There are 236.5882 mL in one US cup. For everyday cooking it's fine to round this to about 237 mL or even 240 mL.
Is 250 mL the same as 1 cup?
Not quite for a US cup. 250 mL equals about 1.057 US cups, so it's a metric cup rather than a US cup. If a recipe just says 'cup' and was written in Europe or Australia, 250 mL is likely intended.
