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.
