I'd be ok with any system that is put into place. I was ready
for metric as a kid in the USA. I'm 43 years old now and it
*still* hasn't happened and once the EU came together, I think
the US has less reason to change over just yet as it's now
become part of "our identity" as 'not the EU'.
Sounds silly, I know... but nations can be strange like that, as
nations are made of people, and people find excuses for doing
things the way they've always done them.
I don't think metric or any system is the magic bullet, and
people who work in Professions use whatever systems their
professions require. The trouble is regular people. People not
accustomed to Imperial get confused when they come over here,
and people over here get confused when they go over to Metric
countries.
I'm sure eventually it'll all even out. Who knows, maybe there
will be a system based upon 7s replacing all the 10s. Stranger
things have happened tongue emoticon
But I'm sure the 10s will win out eventually on a global level.
