What is the standard abbreviation for milliliter?

• A. mL
• B. cc
• C. m
• D. cm

Answer: (A)

The concept tested is how we properly denote milliliters in medical measurements. The milli- prefix means one thousandth, and when attached to liter (the liter symbol is L) you get the unit milliliter, abbreviated as mL. Using a lowercase m with an uppercase L helps avoid confusion with similar-looking characters and keeps the symbol distinct from meters or other units. In dosage calculations and most medical contexts, mL is the standard and widely used abbreviation for volume. Related symbols like m (meter) and cm (centimeter) are for length, not volume, so they don’t represent milliliters. The term cubic centimeter, abbreviated cc, is actually the same volume as a milliliter, but it’s not the standard abbreviation today, so mL is the preferred choice.
