Hah... its some fraction of the alleged Diameter of the Earth.  Well that
lets
out having it be the King's forearm (allrightey)... as we sometimes change
Kings...

and (i concede) we all live on the SAME planet (well...maybe with the
exception
of Batz  ;^) .... so we could argur the standard is the same for all...

But hey... who is gonna go around the earth every few years and calibrate it
for
ISO standards... and what about MARS ???

Yes...what about Mars ?  Should THEY be forced to apply such a geocentric
standard ???

My bitch is that when I need to work on a "thing"... there is no way to
determine
visually that the fasteners are english, or metric. So I assume "english",
walk 20 yards
(or is that 18 meters ???)... to the tool crib and get the wrong wrench.

Hey...maybe my problem is not with metric after all... maybe its with
Murphy's law ?

Yes... lets also divide our frequencies by 10's ... instead of two's,
threes... etc.
That would sound great ! (not)
