Thanks for the clarification. It was an error created, not because I 
used a calculator for the conversion, but my digital caliper. That 
error doesn't get a chance to build up making single point 
conversions on the caliper, and is beside the point when one has made 
the choice of rulers between metric and decimal English.

My original point was if the mm increment was attractive to people 
because of its small size, there were at least four 0.010"s in a mm.
