1 ounce equals how many milliliters?

• A. 15 mL
• B. 30 mL
• C. 60 mL
• D. 45 mL

Answer: (B)

Converting ounces to milliliters relies on the fluid ounce conversion: 1 fluid ounce is about 29.57 milliliters. In medical practice, it’s common to round to the nearest whole milliliter, so 1 fluid ounce is treated as 30 mL. Therefore, the equivalent of one ounce in milliliters is 30 mL (1 oz × 29.57 mL/oz ≈ 29.6 mL, rounding to 30 mL). The other numbers correspond to different amounts (half an ounce, 1.5 ounces, or 2 ounces) and aren’t equal to one ounce.
