OK, here's something we should be able to discuss without the usual sexist references to women's underwear and menstrual cycles... Should US technical divers switch to metric? The main reason I see for keeping Imperial units around is inertia. Also, in beginning courses, you don't want to scare off potential customers by making them learn things in metric units. However, once you get beyond basic OW courses, the formulas and calculations are simpler and less complicated in metric. Also, it would make discussions on newsgroups easier and less confusing. Equipment changes would be minimal, all the electronic gear can be switched with a simple push of a button, and the imperial analogue gauges and things would still have a large resale market when changing over.
