Some thoughts ..
(a) all nonsense aside, life would be very much easier, and the system much safer, if we had ONE set of consistent, easily defined/derived units .. even if that would defeat the joys of in-house jargon etc ... and, of course, it doesn't matter an iota what ethnic origins such a system might have ...
(b) with mixed units, the PE folk are reasonably well off .. having been tortured in the initial undergraduate environment we all are quite comfortable with a rigorous application of units and unit to unit conversions ... however, for everyone else in the Industry, it is a recipe for disaster .. as shown by several well publicised events .. Gimli, for one.
Thread creep ... I've totally forgotten what the thread topic was ... a most wonderful aspect to PPRuNe is thread diversion and thread creep ... one picks up some gems of information along the way ...
