Well... I think the good 'ol "English" unit works just fine. But I am old and set in my ways. <br /><br />You developed a "feel" of magnitude when you work with a convention of units. Most of us here in the U.S. knows how fast is 80mph is (some of us do drive that fast <img src="/images/icons/wink.gif" />), but heck do I know what is 120 km/h ???<br /><br />Oh you think it is easy to change the mindset? Wait till you drive on the "wrong" side of street ! Travel to another country and keep trying the currency conversion ratio everytime you ask "how much"? <img src="/images/icons/rolleyes.gif" /><br /><br />Now for those of you "foreigners" say the rest of world uses the SI unit and so should the U.S., I'd say "hog wash" !! May I remind you that it is the rest of world that should follow the U.S. standard & conventions. Afterall, <i>we</i> went to the moon, brought you the refrigerator, automobiles, airplanes, computers, got rid of communism, and introduced Pamela Anderson !!. We did all these just fine with the good 'ol English unit, what have you done for us lately?<br /><br /><br />OK, I've done enough damage.
