US Engineers and Scientists went metric several decades ago, actually. So did the medical profession.


I machined some prototype cylinder blocks, on a boring mill, for the Chevrolet Chevette back in to 70s.
We worked off of German prints from Brazil and had to convert all of the dimensions. There was one calculator in the plant that could make the conversions. The 1st shift guy had limited access to that. I was on second shift, so I had to do it all long hand.

I would be hard put to do it now.
