What is the correct conversion from mL to oz for 1 ounce?

The conversion from milliliters (mL) to ounces (oz) is based on a standard measurement where 1 ounce is equivalent to approximately 30 milliliters. Thus, when converting ounces to milliliters, knowing that 1 ounce equals 30 mL provides a clear and accurate basis for the conversion. This standard metric is widely used in both clinical settings and everyday applications.

Understanding this relation is essential for nurses and healthcare professionals to ensure accurate medication doses and fluid intake calculations. The other options represent measurements that either exceed or fall short of the standard conversion, confirming that 30 mL is the correct measurement for 1 ounce.
