About milliliters to cups conversion
Recipes written for metric kitchens give milliliters, while American recipes use cups. This converter uses the US customary cup, exactly 236.5882365 mL, so 250 mL comes out slightly over one cup. Liquids convert cleanly, but cups of dry ingredients vary with density, so weigh them when precision matters.

Tips
- Australia uses a 250 mL metric cup, which is about 5.7% larger than a US cup.
- A US tablespoon is 14.79 mL, and 16 of them make one cup.
- Gallons, quarts, pints and cups are US customary units. UK imperial units are about 20% larger and are not supported.
- Converts volume to volume only. Converting to weight needs the density of the material.
- Tablespoons, teaspoons and fluid ounces are not available.
- Results show up to 6 decimal places. Values are not rounded during calculation, and a non-zero result that would display as 0 is shown in scientific notation.
