What is the abbreviation for Millimeter?

Explanation:
Millimeter is a length unit in the metric system equal to one thousandth of a meter, and its standard abbreviation is mm—the two lowercase m’s. This pairing keeps the unit clearly as a submultiple of the meter (m) without confusing it with the symbol for meter itself. In clinical practice you’ll use mm for small measurements, such as depth or dimensions of devices or wounds. Be aware that other abbreviations shown aren’t length units: D5W is an IV solution, min stands for minutes, and Na1 isn’t a standard medical abbreviation.
