In what ISO spec/standard/??? is that convention given?

I suspect it is strictly informal, as the convention violates the SI 
rules: "A multiple or sub-multiple prefix, if used, is part of the unit 
and precedes the unit symbol without a separator. A prefix is never 
used in isolation" - BIPM, SI Brochure, Section 5.1;
