One cup (8 oz) is equal to how many milliliters?

• A. 240 mL
• B. 480 mL
• C. 120 mL
• D. 8 mL

Answer: (A)

Converting cups to milliliters hinges on the relationship between fluid ounces and milliliters. A cup equals eight fluid ounces, and one fluid ounce is about 29.57 mL. Multiply: 8 × 29.57 ≈ 236.6 mL, which is commonly rounded to 240 mL for convenience in cooking and medical math. So one cup is about 240 mL. The other values are off because 480 mL would be roughly 16 fluid ounces (a double cup), 120 mL is about half a cup, and 8 mL is far smaller than a cup.
