An order calls for 1200 mL of water by mouth daily. How many ounces is this?

• A. 20 oz
• B. 30 oz
• C. 40 oz
• D. 50 oz

Answer: (C)

Converting milliliters to ounces relies on a simple volume conversion. In clinical practice, 1 fluid ounce is treated as about 30 mL. So you take the total milliliters and divide by 30 to get ounces: 1200 mL ÷ 30 mL/oz = 40 oz. That gives a daily intake of about 40 ounces. If you use the exact conversion (29.57 mL per ounce), you’d get roughly 40.6 oz, which rounds to 41 oz, but the common approximation used for these questions yields 40 oz, which aligns with the closest option.
