Gimp works in pixels, not millimeters. The physical units are fairly virtual, they are determined by the "print definition" that relates pixels to physical units.
So when you copy/paste, you copy pixels from an image and paste pixels in Gimp. This number of pixels is what is constant. Pasting in physical units between images would require the images to also have the same print definition (pixels/mm or pixels per inch (PPI)).
In addition Gimp will always round things to an integer number of pixels...
