How much fluid is equivalent to 1 cup in milliliters?

One cup is widely accepted to be equivalent to 240 milliliters. This standard measurement is used in cooking and nutritional contexts to provide consistency across recipes and serving sizes. Knowing this conversion is particularly useful in nursing and healthcare settings, as accurate fluid measurement is essential in medication administration, IV fluid calculations, and patient care.

The other options do not accurately represent the conversion from cups to milliliters. Therefore, 240 ml is established as the correct answer. Understanding this foundational knowledge helps ensure proper fluid management and gives better insight into solid dosages and nutritional intake.
