There are also diagrams where m (milli, 10^-3) is used to
represent mikro (10^-6). Even worse and confusing are those, where
mmF gets used when pF (pico, 10^-12) is meant.

Huh? What's confusing about micro-micro farads? :-):-)

Among the odd markings:

- in the 60ies it was fairly common to use kpF (kilopicofarad) to mean nF
(nanofarad)
- in the 30ies, German power mica capacitors were marked in centimeters (cm). 1
cm is equal to about 1.1 pF
