Another mistake that doesn't deserve a top-level comment: the unit abbreviation for "second" is "s", not "S" (that one's the siemens = inverse ohm = former mho, which was a way better unit than the siemens, but that's another discussion...). Thus, "ms" and "ns" rather than "mS" and "nS". This may sound incredibly pedantic, and it is, but it's also one of the tests for attention to detail that I use when interviewing and evaluating an EE candidate, so, y'know, maybe worth learning to get right. Or not, life's short and building stuff out of discretes is more fun. Your call!
I would oppose a unit that starts with a prefix symbol (m=milli=0.001) on principle.
The unit name isn't usually important. I think you're talking about the symbol? That's "℧", which has its own problems. But at least it's in Unicode now! Altogether I think the "℧" caused much less trouble than the "S" has. "S" is just stupid... as evidenced by this whole subthread. And, yes, I have read datasheets wrong because of this. Thanks, 14th CGPM!

Hadn't heard of "mho" for conductivity, is that from when Bourne worked with electronics? :)

Wikipedia dates the mho to 1883 and Lord Kelvin:

The fundamental SI unit of mass is the kilogram (kg).
Thank you, fixed.
