Milliliters are common units of liquid measurement in the metric system. Ounces are commonly used to measure liquids in the standard American system of measurements. Medications and medicine-dispensing tools may be marked in either milliliters or ounces. You may have to convert between the two types of measurement if your prescription calls for one type of measurement, but your measuring tool displays the other measuring unit. You can perform this conversion by using the conversion factor of 30 milliliters per ounce.
