Just in case anyone is confused by this: (maybe it's just me?)

    // Alan's notes:
    // I'd like to put a mu in here for micro.
    // Should we adopt the questionable Electrical Engineer policy of using
    // "u" to indicate micro?  I've added "uF" for microfarad later on to
    // tackle the most common case.
This is referring to using the practice of using the character "u" instead of "µ" as the SI prefix for micro-, presumably because it's easier to type 'u' or because a lot of stuff is still stored in ASCII. Notably, this appears to be the only SI prefix that uses a non-Latin character, thus the inherent problems when used in documents/systems that only support the Latin alphabet or otherwise make it difficult to use non-Latin characters.

Disclosure: Graduate of EE. Didn't know we were causing so many issues all this time with our rebellious use of microfarads :)




Speaking of questionable EE conventions, why do electrical engineers seem to never use nanofarads? 10 nF capacitors are usually labeled as 10,000 pF or 0.01 µF, for seemingly no good reason.

Also, the ohm symbol is frequently omitted from resistance specifications. 10 kΩ is written as 10 k (or worse, 10k).


Other EE annoyances: capacitors are often marked with their capacitance as, say, "100 MFD". No, it's not megafarad, it's not millifarad; it actually means microfarad! That's annoying in several ways, including really abusing the SI prefixes (milli is "m" and mega is "M") and because the symbol for farad is simply "F", not "FD".
