I find this attention to physical units a bit improper. Sure, some
drawing applications or text editors should be enabled to draw UI
following specific physical dimensions (like, for example, for the ruler
bars), but I think it's more of an isolated case than the norm.

Most UIs won't set a button's height to 1 cm (or any other physical
size), because while such a size might be OK for a desktop + mouse
system, it would be definitely be too small for a UI in running a
television set and too big for a UI running on a smartwatch.
