Phil Kangas actually said:

I just don't know how to convert minutes to inches.

You can't. Minutes of angle are a function of a
triangle.
Inches are simply a scalar measurement of distance.

That's bad news because both the toe and camber are specified in degrees
but when I measure toe, it will be in inches.

At least when I measure the camber it will be in degrees so I won't be
switching units back and forth.

I know how to physically measure toe in inches (e.g., with a string); but I
don't (yet) know how to measure toe in degrees with a smart phone or
digital level.
