Not sure what you need / if it is possible.
There is a unit editor, bottom of the edit menu, where you can add your own units for the rulers/measure tool.
As well as the unit editor, the settings are held in the unitrc file in the Gimp profile. It says not to edit but of course you can.
After messing about, I still can not get my head around how the scale factors work. What I think is logical ie 1000m = 39.37 x 1000 inches does not work.
A crazy value of 1 (same as an inch) gives me a km scale. On a map example, I can measure in km.
However, you still can not escape print size and ppi. Your 4096 x 4096 canvas @ 96 ppi comes up at 40 km square, so you will need to set some large ppi value to get a desired size.
Not difficult but messy. you will just have to experiment (if that is what you want)
