The metric system makes a lot more sense.The European way of stating tank 
sizes by actual volume and pressure in bars makes for very easy calculation 
of how much gas is in a tank. Come to think of it, that would probably get 
several cave instructors' panties in a wad (that didn't take long, did it?) 
because they make a living teaching this "magic" in the US system. I can 
just imagine getting the NE wreckdivers (some of whom we still can't even 
get to put manifolds on their doubles) to change, and in FL "73.17 Meter 
Grotto" just doesn't have the same ring to it.

I'm all for it, and would buy new pressure guages and change the markings 
on my stage bottles if my buddies would.
