    Re: SI Units
    From: Marcel Tschudin

    Using SI units has the advantage of knowing what one is dealing with.
    A kilometre is always the same kilometre. However, a gallon is not
    everywhere the same gallon and a mile not every where the same mile,
    it thus requires first to figure out which could be meant.
    
    There are more of those odd things. At least a million is every where
    the same but a billion and higher values not.
    
    And how about the cars driving on the "wrong"side? But this is
    unfortunately not a subject of SI units.
    
    Marcel
