Measurements in Markups Module

Operating system: Win10
Slicer version: 5.0.3

I was wondering if there is a way to show the measurement of length from a Closed Curve divided by 3.14 in order to have the average diameter from the shape. This would be very productive while analyzing aortic diameters with intraluminal thrombus.

Here is an example of what I can do with current measurements. I would like, however, to show the CCs with the average diameters, easily dividing by pi.

Thank you in advance,
