30 milliliters is equivalent to how many fluid ounces?

• A. 0.5 fl oz
• B. 2 fl oz
• C. 1 fl oz
• D. 0.25 fl oz

Answer: (C)

Converting between milliliters and fluid ounces uses the practical rate that 1 US fluid ounce is about 29.57 mL. So 30 mL is just a hair over 1 fluid ounce (30 / 29.57 ≈ 1.01). In everyday use, that rounds to 1 fluid ounce. The other options are significantly smaller or larger than 30 mL (for reference, 0.5 fl oz is about 14.8 mL, 2 fl oz is about 59.1 mL, and 0.25 fl oz is about 7.4 mL). Therefore, 30 mL most closely corresponds to 1 fluid ounce.
