Anyone know the meaning of "gauge" when talking about the outer diameter of a door hinge's knuckle?
For example, commercial door hinge knuckles often have "gauge" sizes of 0.134 or 0.180.
Doing my own measurements, I'm guessing that in this context it means tenth-of-a-meter. E.g., 0.134 gauge = 13.4 mm.

But note that there's nothing intrinsically wrong with fitting a completely different type of hinge.
You obviously need hinges explicitly intended for outdoor use. Not like these
It was difficult to pull up by hand, because of the paint and because it's been there for awhile. But I just used a lot of force at the bottom of the door (using a hammer handle to help me pry up) and I was able to start moving it and then got it off.

The gauge is a measure of the thickness of the hinge metal.

This would affect the size of the knuckle as it wraps around the hinge pin.
Heavy weight gauges increase available bearing surface area. It will also determine the depth of the cut-out recess(es) in the door/door frame necessary for a flush installation.
The gauge also determines the type of 'hinge tweaker' tool you need.
