Can you point one even ONE machine shop in the US that can make metric
parts?  Those guys would have gone out of business years ago.   Also
how many are still using hand cranks and reading veneer scales?   Even
small one man ships are using CNC now.

The US is slowly converting.  It will take a long time.  Even now if
you go to Home Depot and look at plywood you see the better (non
construction) grades sold in even millimeters with the inches being
some odd number of 32nds approximation.   This will slowly creep into
more and more products.

So the debate is silly.  If the US should convert???  No.  the only
question is how fast are we converting and when will we be fully
converted.   Not even if this will happen, it will.
