Happy Metric Day. And a hat tip to David Parker of Metric Machining and Mike Preston of Micron Manufacturing.
And to all of the engineers, machinists and technicians who call the metric system “theirs.”

You may not know it but on this day in 1973 Ohio became the first state in the U.S. to post metric distance signs along I-71.

Back in the day...

These new signs showed the distance in both miles and kilometers. The metric system, though standard in many nations around the world, never quite caught on in the United States, except on major-league baseball stadium fences — and on that highway in Ohio.
And that is why Richard and Joan Parker in the Summer of 1973 decided to call our company Metric Machining when the company began on September 1, 1973.
