You do you boo but Metrics fucking awesome. It's simple, conversions are super easy, etc. it's just basic numbers. You can thoughtlessly multiply or divide (assuming you could thoughtlessly do that before).
You want a real shite headache? Try translating tenths of inches. I'd just burn the blueprints and tell them to try again.
Serious question about this argument. Try translating tenths of inches... to what? I assume you're not talking about converting to metric because then any unit is problematic, and if you're using tenths of an inch then you're using inches, not something else, so... what's the problem?
The most common place to find .1" is on micrometers. And that's just fine until you need to switch it back to imperial or metric for the next processing...which the rest of your tooling is in.
