You personally, of course not. But if I'm in charge
of outfitting a new production line, maintenance
department, etc., I'm pretty strongly motivated to
eliminate inefficiencies. Having to carry duplicate
tools, etc., in both metric and English is most definitely
one of those inefficiencies, and having to convert
back and forth makes for further time wasting and
potential errors. So I need to pick one, and frankly,
the "English" system winds up being at a disadvantage
there - and yes, I would have to have some justification
for continuing to use it.

Except that picking a system of measurements really
doesn't have much to do with "any other aspect of
our lives," and trying to compare such arguments across
these boundaries is pretty much guaranteed to wind up
an apples-and-watermelons sort of situation.

If you're really talking about density, (mass per unit volume) the
buoyancy of air has nothing to do with the result. If you're talking
about the WEIGHT of a unit volume, then, in some cases, you
may need to correct for the buoyancy of air---which is, of course,
a function of altitude.

That point of decimation brings back memories----when I
worked on highway surveys back in the '60, all the
measurements were in feet---and tenths or hundredths
of feet. Not an inch to be found in the survey logs!

What about measuring time in degrees? How might that work?
Ie. it's 360 o'clock, or 180, or 90, etc.

When are they likely to change over to a metric week of 10 days? Then,
I guess the month should be replaced with a metric month of 100 days
and the year extended to a metric decimal multiple of 1000 days.
