API, OpenAPI and WebMCP documentation

Explanation

The US customary cup is defined as 236.588 milliliters, so this calculator multiplies cup counts by that exact volume before presenting metric answers. That keeps decimals and partial cups predictable while preserving the same base for every volume conversion across the site.

Use it to translate recipes, sauces, or beverage pours into milliliters so metric tools yield the same volume that the cup used. Keeping the defined cup shared across this array of converters avoids drift when scaling between customary and metric units.
