How It Works

The US customary cup is defined as exactly 8 US fluid ounces, and one US fluid ounce equals exactly 29.5735 mL, making one US cup equal to 236.588 mL. To convert milliliters to cups, the calculator divides the milliliter value by 236.588. Because the US cup is not a round metric number, the result is typically a decimal fraction rather than a whole number. The output is rounded to four decimal places, which is more than sufficient for any cooking or baking purpose. A value of 500 mL divided by 236.588 gives approximately 2.1134 cups, meaning slightly more than 2 cups and 1 tablespoon. Note that the Australian and Canadian metric cup equals exactly 250 mL, which differs from the US cup — this calculator uses the US definition of 236.588 mL, so results may differ slightly if your recipe uses a non-US cup standard.
