Well, *now* it is precise. Obviously it wasn't precise when it was 
formulated.  I think the foot, however, was the size of some specific king's 
foot. And the metric measurements have changed definitions over the years as 
well.

Sure, because there are different units, unlike the SI measurements which 
only have one unit per fundamental element being measured. I still have to 
put mental calculations forth to translate between seconds and meters, or 
between meters and light-years, or between watt-hours and watt-months, or 
between moles and grams, because they're different units based on arbitrary 
physical properties. The fact that one has to translate between inches and 
feet isn't really any more of a problem than the fact that metric 
measurements have to translate between seconds and years.
