I wish it was that simple. After moving to Canada, I was doing an off the cuff calculation and said '1 gallon of water is roughly 8lbs'. Imagine my surprise when everyone in the room disagreed with me, saying a gallon weighs 10lb. All was made well when I was reminded that Canadians use imperial gallons. Aaargh. SI is a real international standard, while 'english' units are just a mess. Of course, I am constantly reminded of my US background when I tell the Scouts in my troop to cut a 6' piece of line and get blank stares. They want me to say 2m. At the same time almost none of them can tell me their 'weight' in kilograms. -- James (Jay) Treacy [EMAIL PROTECTED] _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
