Job shops still get a mess of both measures, and they're the ones who
have a right to be ****ed off about it. Otherwise, it's not really a
problem. And keep in mind that our dimensions for length are in
decimal units for most technical things, anyway. It matters little
whether you start with a meter or with an inch if you do that, as long
as you don't have to keep converting. And with computer controls, you
just push a button even for that.

For those reasons, it's mostly a tempest in a teapot. There are some
good reasons to go all-metric, but there are few people who would even
notice.


When I worked as a QA Inspector in a sheet metal shop, one of our
customers was a German owned company. Some of the drawings received from
them had both metric and U.S. dimensions on the same drawing.

I think that a lot of Europeans, and Japanese, with whom I've worked a
lot more, think that we don't understand what metric is, and that we
don't have the tools to measure it.g

A Japanese engineer I used to work with used to struggle with a piece
of paper and a calculator when he talked to me, converting metric
dimensions into inch -- with fractions rather than decimal inches.
Maybe he thought I was a house carpenter.g


After re-reading my post and your reply I think that I should be more
specific. For instance,they would call out the length and width in
metric, then spec the hole distances in U.S., the hole diameters in U.S
with a metric thread. It was not to bad for me but the CNC programmers
and the machinist always complained.
