Is one set up in mm and the other in cm?

How do I check

Your code should have a G21 for Metric or a G20 for Inch, it will be in the first few lines of code but it's easy to search for,

It says g21

Your G-Code is set to metric, that should also cause Mach3 to switch to metric even if it's previously set to inch.
Post the code up here and let's have a shuftie

That code should not run no expert but line 110 looks incorrect

I am no expert but looks ok to me apart from 2 "=" characters on 110 while they are there it should not do anything.

As I read it it cuts inside first then bolt holes then external 20mm offset from internal
