Metric vs imperial

Metric: XXXX.XXX
Imperial: XXXX.XXXX

It doesn't convert your program, it only converts your axis displays.

Switching between G20/G21 has a lot of issues.
It is better to reserve machines either for G20 or for G21.

Older FANUC controls will not convert the registers (position, work coordinate or tool offsets) from inch to metric or the other way around. It only changes the decimal position. In order to reset the registers you need to cycle power. Again in most cases this only changes the position registers to the correct value, wht work coordinate and tool offsets are not converted from one system to the other.

I haven't seen an instace where it will let you perform a G20/G21 switch, unless all axes were at their "Home" position. Its strange that 1- you're trying to switch between units while not at home position, & 2 - that it will let you...
