"The largest print is 85 x 95 x 30mm." Should it be in "cm", not "mm"?

Anything not related to this pull request should probably be a separate issue or pull request, to keep it clean.
To answer the question: The unit should be "mm", not "cm". If it were "cm" it would not fit on the Ender 3 print area of 220 x 220 mm (22 x 22 cm).

I am sorry, I misinterpret the sentence wrongly: I understand that the largest print bed supported for this calibration is 85 x 95 x 30cm.
But this sentence actually means, that largest printed object during this (calibration) process will be 85 x 95 x 30mm.
I am sorry, my mistake...
