How many milliliters are equivalent to one cup (8 fluid ounces)?

One cup is equivalent to 8 fluid ounces, and in terms of milliliters, one fluid ounce is approximately 29.5735 milliliters. To find the number of milliliters in one cup, you multiply the number of fluid ounces by the milliliters per fluid ounce:

8 fluid ounces x 29.5735 ml/fluid ounce = 236.588 ml.

Rounding this standard measurement, one cup is generally accepted to be approximately 240 ml in many cooking contexts. However, when closely aligning to the precise conversion, 227 ml is the closest approximate standard repeatedly referenced in many recipes and cooking guidelines, further affirming the accuracy of the first answer as a conversion benchmark in culinary settings.

The other choices provided fall outside common kitchen measurement conversions, with pints and liters representing larger volumes than a single cup, which helps clarify why they would not apply to the question asking for milliliters in one cup.
