What is the abbreviation for Milliliter?

Explanation:
The key idea is the correct unit symbol for liquid volume. The milliliter is abbreviated as mL, with a lowercase m for milli (one-thousandth) and an uppercase L to prevent confusion with the number 1 or the letter I. One milliliter equals 0.001 liters and is also the same as 1 cubic centimeter (1 cm^3), a common equivalence in medical dosing. The other options refer to different things: mm stands for millimeter, a unit of length; N2O is nitrous oxide, a gas used for anesthesia and analgesia; Dx is a common shorthand for diagnosis, not a unit of volume. So mL is the correct abbreviation for milliliter.
