This converter supports multiple cup standards. A “cup” is not the same everywhere, so the correct conversion depends on the standard used in your recipe.

Choose a cup standard:

• US Cup = 236.588 ml (common in American recipes)
• Metric Cup = 250 ml (common in Australia, Canada, NZ, and many modern sources)
• Imperial Cup = 284.131 ml (older British-style measurement)

Use the dropdown in the calculator to match your recipe’s region.
