== Infobox. == 

 I don't like that the infobox shows decimal units for the number of inches in a foot/yard/mile.  Those are approximations only - the true definitions (ie 1/12th ft, 1/32nd yd, etc) should be given.  That is both clearer and more accurate (indeed infinitely accurate) - and would be far less confusing to someone coming from the metric world who truly wants to know how many inches there are in a yard or whatever. 
 You could put the decimal expansions afterwards or something - but the way it is now sucks.
