Drew,
It would be better if the rest of the world adopted Imperial measurements.
Speaking as an Englishman who uses both, Is it not more accurate to have a measurement with increments of a thou than a rounding of to a fraction of a mm.
I guess it depends on which you use as to weather you think its more accurate - they are both accurate if used properly. But still something i've often pondered knowing damn well it made no bloody difference. The good news is the vast majority of machine tools and feed/speeds are still in Imperial measurements.

There was a guy over here in Newcastle UK who kept selling in pounds to his customers and the council took him to court for breaches in wights and measures, they hounded the poor guy - He unfortunately committed suicide as a result of the burden of court costs and loss of business as a result of being shut down.

Funny how you can still buy a pint of beer or milk and road signs and car speed's are still in MPH. One day someone will get a medal off the queen for switching to use both measurements as an indication of our multi national trade. Who ever said the EU were controlling ?
