I think the answer to this question rests on the meaning of = in
   8km = 5miles

(pretending that the arithmetic is precise and correct)
Conceptually I think we could have units:kilometer being a datatype 
whose value space is distances and whose lexical space is the same as 
xsd:decimal, and its value space would (modulo rounding) be the same as 
units:mile but disjoint from units:squareMeter ...

However I defer to others ...
