The formula
How to convert milliliters to cups
To change milliliters into cups, multiply by 0.004226752838.
cups = milliliters × 0.004226752838
Going the other way: milliliters = cups × 236.5882365
1 milliliter = 0.00422675 cups. This factor does not end, so results on this page are rounded.
Worked example
You have 250 milliliters. Multiply by 0.004226752838. 250 × 0.004226752838 = 1.0567 cup.

Before you rely on it
US cups, and the 250 mL metric cup
This page converts to the US customary cup: exactly 236.5882365 mL, which is 8 US fluid ounces. It is the cup in American recipes and on US measuring-cup sets.
Australia, New Zealand, Canada and most metric recipes use a 250 mL cup, about 5.7 percent bigger. If a recipe was written in metric cups, 250 mL is simply 1 cup and nothing needs converting.
US nutrition labels round the cup to 240 mL. A serving shown as "1 cup (240 mL)" is the labelling convention, not a different cup.
A cup measures space, not weight. 250 mL of flour and 250 mL of sugar fill the same cup but weigh very different amounts, so milliliters to cups works for liquids and for anything you measure by volume, never for grams.
