"mA's" and "mW's"

I don't want to be the grammar nazi here, but some people are just falling into bad practice because they see others doing it. So...

Where did the apostrophe s come from? Do you abbreviate inches as in's? Do you abbreviate pounds as "lb's"? Leave it off. The plural is the same as the singular.

Also, Asking "how many mA?" or "how many mW?" is like asking "how many feet and inches are you?" It sounds a bit strange.
It should be said "what current?" or "what power?" just as "how tall are you?"

If you're confused about how to use an apostrophe, see this page

Thank you :yh:

One milliAmp and 100 milliAmps does not seem the same to me
when usung the long form....

mA is an abbreviation of milliAmpere shortened to milliAmp...
and when using the abreviation it should be mA whether singular
or plural....
Therefore it would be 1 mA and 100 mA... IMO

Same logic for mW......

But using an apostrophe after mA or mW is totally wrong...
's implies "belonging to" as in John's Laser
(Laser belonging to John).

BTW... are you sure you're not the Grammar Nazi.... :crackup: :crackup:
