Slight discrepancy in measurment between Rhino & Moi?

Hi

When I copy and paste just a regular rectangle from rhino to moi the measurements are not translated to the same amount. This also happens when I open the file or import the file.

I may have 120.00 inches in rhino , but when imported to Moi it is 120.25 even sometimes an inch of discrepancy.
thus messing up up my pipeline

am I doing something wrong?
thx
