Milliliters to Cups Calculator

Converting milliliters to US cups is one of the most common stumbling blocks when following American recipes outside the United States. A recipe calling for two cups of broth or a quarter cup of oil uses a unit that most of the world's measuring jugs do not mark. Home cooks who only have metric equipment need a fast, reliable way to convert those cup values to milliliters — or the reverse when they want to express a metric ingredient quantity in US cups for an American friend. Food bloggers adapting international recipes for US audiences routinely use this conversion. Baristas calibrating espresso-based beverages for US customers translate their milliliter yields to cups. Dietitians tracking fluid intake with patients who think in cups convert medical records given in milliliters. This calculator uses the exact US cup definition of 236.588 mL. Meal prep enthusiasts batch-cooking large quantities, and nutrition app users logging liquid intake in cups while their measuring tools are labeled in milliliters, will find this converter an essential kitchen companion.

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.
