Which metric unit is commonly used for measuring liquid medications?

Milliliters (mL) are commonly used for measuring liquid medications because they offer precision in dosage, vital in pharmaceutical contexts. Liquid medications often need to be dosed in small quantities, and milliliters provide a convenient scale for measuring these smaller volumes accurately.

Grams are primarily used for measuring solid substances rather than liquids. Liters are suitable for larger quantities but may not be practical for the small volumes typically needed in medication dosing. Ounces, while sometimes still used, are less standardized in the medical field compared to metric measurements, which are preferred for their clarity and universal application in healthcare. Thus, milliliters stand out as the most appropriate choice for liquid medication measurements.
