- Milliliters
- 236.5882
U.S. cups multiplied by 236.5882365.
How cups to milliliters conversion works
This calculator uses the U.S. customary cup, where 1 cup equals 236.5882365 milliliters.
It multiplies cups by 236.5882365 to estimate milliliters.
Cup sizes vary by region. If a recipe uses metric cups or another regional cup size, use the conversion expected by that recipe.
