By no means are you being an asshole, but I do understand the implications of what you're saying; I just don't agree since every measurement is given on first use. So I'd expect an Australian to understand one of my articles on a pre-metrification Australian ship just fine. Your argument, and that of the MOS itself, has a great deal more merit when no conversions are given so that people can't grasp the scale of things properly. Since my articles can be fully understood by people on both sides of the Imperial/metric scales, I view it more as a matter of taste. And, quite honestly, since I have a large number of FA, A-, and GA-class articles under my belt, most reviewers seem to agree as no one's ever challenged me on this particular point before.
