It’s the same as wire gauge, but the scale is different per material!
For steel
16g = 1.5mm
22g = .75mm
And so on
Pretty much anything larger than 1/8th of an inch (3.2mm), we just use the measurement (in inches).
Why? Because we don’t have a common measurement unit smaller than an inch. There probably is one, but no one commonly uses it.
Coming up with a gauge scale is actually easier than say .0123 inch thick. Say “12 gauge wire” and everyone (who knows about it), knows exactly what you’re talking about.
Pretty much anything below 1/32 (0.8mm) of an inch, we’ll switch to decimals.
0.0001 inch is valid with no common way to make that neater. No such thing as 1 mili-inch.
Oh! I just remembered that the size of shotgun shell pellets are calculated that way. Take a fixed amount of lead and the gauge (we call it caliber) og the pellets is defined by how many of them you can make from that lump of lead.
Here in Norway it’s more expensive to live than ever. The interest is high and all other prices on have balooned this year, so the prices are too damn high. But I guess that is true for most countries.
Many people believe we are on the verge of a housing bubble bursting within a few years, so that might be a good time to relocate.

.001" is a thou or mil (1/1000 of an inch). That is commonly understood in any industry that requires that precision and also doesn’t already work in metric by default. 0.0001 would be 0.1 thou, but honestly any time I’ve ever seen anybody need more precision than a whole number thou, they worked in microns or nanometers.
With the Sheet Metal Gauge!

Remind me, what is the cost of living in Europe?
