<div>There is an 'alternative' degree system where a full circle
is 400 degrees and a right angle is thus 100 degrees instead
of 90. I haven't played with the math implications, but it
seems logical that all triangles in such a system would have
angles adding up to 200 degrees.</div>

<div>If they had listened to Jefferson we would not be
messing with a double system, metrics would just be
what we use... The 10 based system can be done in
your head (could have saved all those years learning
those damned fractions) :-) and every tool box
wouldn't have a fraction to decimal conversion chart
tucked in somewhere that you can't ever find when you
need it. Also we would not have to worry about some
dead kings thumb size getting lost or a bad few years
for the barley crop or a lot of other stuff they tried
to set as standards long ago.</div>

<div>This site looks fairly well done and I liked the
little section on the metric size of a few common
objects.</div>
