A couple old metrology equipment dated back from the 80s I still use calls them ‘mil’. It’s got dual dials for mil/mm. Gets me confused sometimes because the gauge can go down to couple millionths of an inch/couple 10s of nanometers.
Yeah, I’ve never heard of that before either. What I have heard of is either MOA or MIL reticles. In that context a Mil stands for milliradian, which is a representation of angle. That definitely doesn’t track with the post though.
And it’s especially confusing for people who use sane measurement systems where “mil” is short for “millimetre”, because it’s just the start of the word. I think anyone that still insists on measuring things in thousandths of an inch should keep their own bespoke lingo too, and everyone else should steadfastly refuse to acknowledge “mil” in this context.
Probably one thousandth of an inch.
I’ve heard it referred to as ‘thou’ but not ‘mil’

LVDT for those curious.
