How it is calculated
Metric cup: 1 cup = 250 ml
US cup: 1 cup = about 236.6 ml
Cups to milliliters: multiply the cups by the cup size
Milliliters to cups: divide the milliliters by the cup size
Recipes from different countries use different cups, so choose the type that matches your recipe.
Worked example
2 metric cups × 250 = 500 ml
2 US cups × 236.5882365 ml ≈ 473.18 ml
250 ml ÷ 250 = 1 metric cup
Why your number may differ
Metric and US cups differ, so picking the wrong type gives a skewed result. Measuring cups in your kitchen can also vary a little between brands, and how you scoop dry ingredients changes the real amount.
