Understanding mL to Cups Conversion

Need to convert mL to cups for a recipe or cooking measurement? You’re not alone — milliliters are used in most countries, while cups (the US customary cup) are common in many recipe books and online recipes.

The conversion is simple. One US cup equals 236.588 milliliters, so the mL to cups formula is: cups = milliliters × 0.00422675

Examples you’ll use often:
