.....different kinds of mile, there is only one kilometre so that such confusions don't occur in the SI >metric system.This precisely has been my concern - 'avoid confusion' right from, during formitive years of a child's mind.
My suggestion to consider Earth as a *hypothetical sphere* of radius 6371 km and considering this to be 36000 km' (kilometre new (km') is what I mean by redifining the length unit 'New METRE (m') as: 1/10^5th of arc-angle ONE degree; and equal to the distance:
"�Metre (m') is the distance traversed by light, in vacuum, during the time interval, 1/97059575.22TH of the decimal second�. Since�1/100TH of one degree� is to be the Nautical Kilometre; length distance METRE can be seen as 1/100000th of the degree."
Here Decimal Second (sd) is 36% of SI-Atomic Second.

*****The New Calendar Rhyme*****
Thirty days in July, September:
April, June, November, December;
All the rest have thirty-one; accepting February alone:
Which hath but twenty-nine, to be (in) fine;
Till leap year gives the whole week READY:
Is it not time to MODIFY or change to make it perennial, Oh Daddy!And make the calendar work with Leap Week Rule! ***** ***** ***** *****

Ron,
Relevant to our recent exchange of ideas on the use of metric in reporting about the Gravity Probe-B spacecraft, I ran across a piece of information that I'd like to mention. In a recent NASA publication I learned that the 400 mile high orbit of GP-B which you reported (and which I had suggested could be identified as a 650 km orbit) is really a 400 NAUTICAL mile orbit (which is closer to a 750 km orbit).
Since our previous discussion centered in part on what units are familiar to your "average reader", I think it is important to realize that most "average readers" are probably even less familiar with the nautical mile than they are with kilometres. Furthermore, instead of two (or three or four*) different kinds of mile, there is only one kilometre so that such confusions don't occur in the SI metric system.
I think your argument that you want to use units familiar to your readers loses its persuasiveness when you use nautical miles (especially when you don't identify them as being the nautical type of miles).
Regards, Bill Hooper
* PS I have found references also to: statute miles, surveyors miles, British miles, Roman miles, international miles, land miles, and my personal favorite the "missizazgoodaza mile". :-)
