The errors I found were in Table 2 titled "Examples of SI Derived Units" and are the following two entries:
resistance ohm V/A conductance siemens S A/V, -1
and in Table 3, "Prefixes", in this entry:
10-6 micro
The errors are the omission of the Greek letters capital Omega (in two places) and lower case mu (in one place). Also, the exponents on various units raised to power as well as the powers of ten used, are all on the line instead of being raised.
Thus, resistance above should have the capital omega < Ω > after the unit name ohm, to show that it is the symbol for ohms. Conductance (on the next line) should have an omega before the -1 to show that both
amperes per volt (A/V) is one thing that siemens is equivalent to and that ohms raised to the minus one power < Ω-1 > is another thing that the siemens is equivalent to. (I can't show the power as a raised number on my computer either.) Finally, the symbol for micro < µ > is missing from the line for the prefix micro in table 3.
Numerous examples occurred where exponents were used and did not reproduce as exponents including all the powers of ten listed in the table of prefixes).
(Of course, I can't be sure that these things were wrong as received by YOUR computer. Perhaps your copy did not have these errors. And of course, my own computer has the same kinds of possible inconsistencies with your computer so my Greek letters capital omega < Ω > and lower case mu < µ > may not be correct as you read this although they are correct on my computer as I write it. This was not meant to start another discussion of the difficulties in transmitting special characters by email, but just to suggest that, if you find Bob Nelson article helpful enough to keep, you may want to correct these transmission error by hand or something.)
