Hi - Can somebody please verify that my understanding of European
resistor value notation is correct? My understanding is that the
magnitude (K/M) replaces the period, so 1K = 1K0, 1.2K = 1K2, 15M =
15M0. Also, when there isn't a magnitude (value under 1K) then an R is
added to the end - so 500 ohms = 500R, 10 ohms = 10R.

Is this all correct?

Yes.

Why are there two different notation schemes? To me the European
version seems unnecessarily complicated. I just don't see a need for
it.

It is simpler in Europe.
Americans still specify small caps in uF, and then say .001 uF,
we say 1nF.

Not true. We use the quainter nFs when needed, but we've mostly
moved on to gigafarads these days for cleaner signals. You guys should
try them.

What I don't get is Europeans--is it true you're still using those
antiquated Indo-Arabic numerals...and even Phonecian letters turned
this way and that, willy-nilly? How can you recognize your aleph
(oxen) when they're upside down, or houses on their sides?
