Definition
A lower-case m has several possible meanings on a Safety Data Sheet. The most likely uses are:
Mouse - this is used to indicate which kind of animal was used in toxicity testing. Usually written as a lower-case m. See an example under SDS Relevance below. RTECS uses the abbeviation mus for mouse.
Molality, a unit of concentration. While this is correctly written in lower-case italics, m, remember that plain text files do not support italics. Do not confuse this with closely-related molarity, which is capitalized M.
Meter - a metric unit of distance; generally unlikely to appear on an SDS as a distance unit except perhaps as a minimum safe distance.
Do not confuse m with m3 = cubic meter, a unit of volume, which can appear as m3 in plain text files that do not support sub- and superscript characters.
