Technically, we did...sort of.
Here in the non-committal US of A, both metric and "English 'ft & inches'"
measure are legal and acceptable--simultaneously.
Some industries, primarily automotive, converted to metric over time. When
I worked at a Chevrolet dealership in the early 80's, bolts painted powder
blue were metric. They were painted so the technicians knew what bloody
wrenches to grab. I have seen cars where the left front shock mount bolts
were 3/8", and the right front 10mm. Now they're all metric.
The town that I grew up in started posting speed limits in both mph and kph.
problem was, somebody boo-boo'd the conversions, so you dould do , say 37
mph in a 35 zone. If ticketec, you just claimed that you were under the kph
limit posted. If the officer was there, you could nail him/her by asking
the metric conversions to various speeds, which they couldn't normally
answer.
Personally, I wish we wouldn't be so bloody arrogant in the US. Teach both
systems in school for twenty years, while doing a gradual phase in, they
just go metric. It's a lot easier.
The soapbox is open.
Asbestos underwear is on.

PS for Harry M--Is there a scanner list anywhere in the US that you're not
on??

Weren't we supposed to be converting to metric about 20 years ago (520
fortnights for those who prefer more traditional measurements) ;-}
