How to convert cups to milliliters
One US customary cup is 236.588 milliliters, so multiply cups by 236.588 to get milliliters. For example, 2 cups × 236.588 = 473.2 mL. Many recipes outside the US use a 250 mL metric cup instead, so check which one a recipe means. Cups measure volume; flour and sugar weigh different amounts per cup.
