System Information
Operating system: Linux-5.8.0-2-amd64-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 450.66

Blender Version
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-10-09 21:39, hash: 7ab8d7c939
Worked: not in 2.80 or 2.83

Short description of error
When the unit scale is too low (< 0.0001 e.g. 0.00009), the values in all sliders will jump up to the value they would have with a unitscale of 1.0. This causes problems with the clipping planes of the viewport camera (didn't do this in 2.80). This seems to be independend of the unit system (metric/imperial).

If this is a known limitation then the shown precision of the unit scale slider should reflect that. Also a fix for the clipping plane issue is needed as that did work in 2.80.

Exact steps for others to reproduce the error
Based on default startup.

In Scene Settings: enable seperate units
set unitscale of 0.00009 or less (metric r imperial)
observe what the dimensions sliders tell you about the dimension of the default cube.
observe the buggy floor grid in the viewport probably due to the same bug in the clipping sliders (wasn't there in 2.80)

Thanks for the report, I can confirm that the sliders show a different value than expected.

I'm not sure if the problem with the buggy floor grid is really related, but it's worth noting.
This other problem has already been reported in #80048
