I was having lunch yesterday with some of my woodworking friends, one of them recalled being in a Jr High science class that was teaching the Metric system and the teacher said that it was comon knowledge that the Metric system would be instituted in America by 1985.   He lived in a smaller town of 40,000 or so that was really a tight knot community, so it was common to see your old teacher at the stores and restaurants, this guy threw that statement up to the guy until recently when the teacher passed away.

Duckie I have two sets of those and other iterations of that from other manufacturers.  I find them very useful....they hang in a place of honor in my home "hardware store.
