If anybody's interested, Sherry your comment inspired me to make a little
macro which is expandable, but currently can convert any combination of
"mm", "cm", "m", "km", "in", "ft", "mi". I posted it here, and then as
usual found a minor error in a #debug statement & then re-posted.  I
wouldn't mind contributing this, realising it may need modification to fit
the standard we come up with. Any comments for improvement?
