Bill,
I would prefer L/100 km, which, if converted to SI would be m². This would be dead easy to visualize. Assume that fuel consumption is 10^-6 m². This works out at (1 mm)². Now imagine a string of fuel snaking along the road that you are using, square in cross-section with each side of the square being 1 mm. Now imagine that you are driving along that road. As you drive along the road, the string of fuel will be fed into your engine and will propel your car. I have not worked out what the cross-section would really be, I merely used 10^-6 m² as an example. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Potts Sent: 28 January 2008 06:20 To: U.S. Metric Association Subject: [USMA:40255] Re: convenient numerical values J.

Maybe so (and we had a discussion on this list a few years ago, involving that same ultimate reduction), but it is something that neither the physicist nor the layperson can readily visualize (although the physicist can rationalize its use).
