It's also not the standard, even though it's a university site. Even the non-technical and non-scientific Wikipedia is smarter here: http://en.wikipedia.org/wiki/Micro And whoever thinks that in the 50ies or 60ies the use of 'm' for 'micro' was understandable because 'milli' was not yet around should look at this: http://en.wikipedia.org/wiki/Milli -- they claim that 'milli' was adopted in 1795 :) Not sure this really holds true, but it definitely is older that most of us here.
