API, OpenAPI and WebMCP documentation

Explanation

This converter uses the US customary cup standard (1 cup = 236.588 mL). To convert milliliters to cups, divide the milliliter value by 236.588 to get the equivalent number of US cups.

Common kitchen conversions include 100 mL, 250 mL, 500 mL, and 1,000 mL (1 liter). Results often show decimals because most metric amounts don’t map to neat cup fractions.

If a recipe specifies a metric cup (250 mL), the result will differ slightly—this page always uses the US cup for consistency across cooking converters.
