Then he should learn to write it correctly.  "M" stands for mega, "K" for
kilo, "m" for milli, and the greek mu for micro although it's perfectly
acceptable and common to use "u" since it looks similar and is directly
available on many keyboards whereas mu isn't.

Yes, but that was long long ago.  Back then you never saw millifarads or
nanofarads either, so anything with a M was unambiguous.  Sometimes even
values like 100pF were written as .0001 microfarads.  Fortunately those days
are gone.

There is enough confusion in the world, and sloppiness with units causes
real harm.  It needs to be stomped on and pointed out for the stupidity it
is whenever it comes up, especially considering that's it's no harder to get
it right.  In this case doing right would actually have been easier since
apparently this guy meant "uF" when he wrote "Mfd".
