Actually, in some instances, RPM can refer to "rotations" but that s typically on a 4 or 5 axis milling machine where you are describing the maximum rotary speed of an axis. Admittedly this is a very small instance.

Websters dictionary defines "RPM" as revolutions per minute, not rotations
or revolutions's, so your engineer is wrong, unless of course he is
developing an entirely new language, and you would be wrong if you use
"rotations" to define the acronym; although, this acronym is so common, it
probably would not need defining.

I'm having a back-and-forth with an engineer about how to write more than
one RPM. She wants to write, "RPM's." I freaked and said, "No, that would
be saying, it's the Rotation Per Minute's problem."
I know, it doesn't make sense.
I want to simply write RPM, meaning Rotations Per Minute.

Am I correct or is there another way?

I also hate to apply the possessive to an inanimate object or a company
for example, "IBM's net worth." Is there a rule about that, or is that
just me?
