They are to give equal priority to all roads at a junction, usually where
traffic flow would block traffic from side roads.
I was trying to offer a universal model that would accommodate both "true"
roundabouts and mini-roundabouts.
In the UK you are expected to make an effort to drive around the "dustbin lid"
(painted circle) in the middle of the mini-roundabout, but that only makes
sense for smaller vehicles.
The mm is because it's intended do describe water tubes and pipe threads,
and not roads. That is why I have doubts using it for the mini-roundabout.

The Wiki-page for diameter explicitly mentions the use for turning_circle
and
Using mm (millimeters) as a unit for this makes no sense. Meters are much
better in my opinion. I understand water tubes and pipe threads might be
well-stated in mm (for "household" and "everyday" use, not hydrology engineers
and sewerage architects), but water tubes and pipe threads are not
I think the point was that the units are explicitly tagged in meters,
whereas in other cases (like ele), the unit assumed to be meters and you
can just put a number by itself.

The mini-roundabout just adds priority on the MR to the general keep left rule,
that is my understanding.

Diameter implies there is something circular. The paint is often round, not
always, but most are just former T junctions or cross-roads where there is
nothing to measure the diameter of .

Generalising for all roundabouts, I propose a model in which there are three
diameters:
D1) outer diameter, where the outer kerb is
D2) "guide" inner diameter, the outer diameter of the inner ring intended to
"discourage" traffic
D3) inner diameter, where the inner kerb or wall is (not
