I don’t want to extend this thread indefinitely, but I just ran into exhibit 1 :-)

We generally write microfarads as uF instead of ?F because the latter may be a bit harder to type on some systems, and it is somewhat unlikely to actually need “u” (atomic mass units) in conjunction with farads.

Now I ran into a case of hypercorrection [0]:
The manual for a capacitor decade, made by the quite respectable Time electronics [1].
This consistently uses greek prefixes, e.g. in:

μF = Red
ηF = White
ρF = Yellow

You may need to squint, but the u?? (mu for micro) reverse correction, where we add a little stem to the u to make it a mu, was extended to n?η (eta for nano) and p?ρ (rho for pico).
You can’t make this stuff up…

So please don’t try to be *too* correct.

Grü?e, Carsten
