Well, there's a sort of knee-jerk anti metric system reaction, even by
people who never did buy into the "Freedom Fries" mentality.

I assure you my antipathy to the metric system is not at all knee-jerk. (And as you probably know I never bought into that whole Freedom Fries, etc., thing.)

I figure the metric system is good for the pointy-headed scientists who seem to prefer it, but for us ordinary folks, our (U.S.) "customary" measures suit me just fine. I use inches, feet, ounces, quarts, etc., every day in my work.

As a matter of fact, for certain work like carpentry (basically any non-precision work), a system based on divisions of 12 is actually more practical in everyday usage than one based on divisions of 10.
You use a lot more nonsensical dimensions than that!
There's 'Thou's', 128ths, 64ths, 32nds, 16ths, 8ths, quarters, halves of an inch.
There's links, rods, chains, yards, ...
There's grains, carats, tons, US shortweight tons, tonnes and umpteen other weight measurements.
Fluid ounces, US fluid ounces, pints, US pints, gallons, US gallons, hogsheads etc etc.
Each of those, including the hundreds of traditional measurements I haven't mentioned, have irrational conversion factors to many of the
others. Just scaling a dimension like 15' 5 7/8" requires 2
conversions and two additions to get a dimension into a form where
you can begin to apply a conversion factor.
<sheesh>

As usual you miss the point. When I'm working with these units there's no need for conversion, so no problem. You're creating a problem that doesn't exist.


You're modelling full size??? WOW!

I'm modelling New Zealand Railways in 1:24th scale so everything I build has to be scaled one piece at a time.
Original drawings (steam era) are all in imperial measurements, my machinery is metric, tooling metric or imperial and materials are either metric or imperial depending on their source.

The point is that scale conversion is a P... in the A...!
No, direct measurement from the plans isn't practical, given distortions in copying machine output.
