Converting Ounces To Milliliters: 1 Ounce Equals How Many Milliliters?

Converting Ounces To Milliliters: 1 Ounce Equals How Many Milliliters?

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

Answer: (B)

Converting between ounces and milliliters uses a quick-rule-of-thumb often used in healthcare: 1 fluid ounce is about 30 milliliters. So for a 1-ounce amount, the best estimate is 30 mL. If you needed exact precision, 1 fluid ounce is 29.5735 mL, but rounding to 30 mL is standard for practical dosing problems. The other numbers don’t fit because 15 mL is about half an ounce, 45 mL is about 1.5 ounces, and 60 mL is about 2 ounces, none of which match a 1-ounce quantity.
