When converting 90ml to ounces, which conversion factor is used?

To convert milliliters (ml) to ounces, understanding the conversion factor between these two units is essential. The correct conversion factor is that 1 ounce is equal to 30 ml.

Using this factor, when you want to convert 90 ml to ounces, you would divide 90 by 30. This calculation yields 3 ounces (90 ml ÷ 30 ml/ounce = 3 ounces).

Using the other options would lead to incorrect conversions. For instance, if you used a factor where 1 ounce equals 10 ml or even 15 ml, the resulting calculations would not align correctly with standard measurement conversions used in clinical settings. Therefore, it is vital to use the accurate conversion factor of 1 ounce equaling 30 ml, as it ensures that measurements are appropriately represented when converting between metric and imperial units.
