How to get a dimension artboard and selection with UnitRuler.Milimetter?

When i use app.activeDocument.width & app.activeDocument.selection [0] .width  it returns the pixel parameter

You would need to multiply the ratio of whichever unit you like, by making it proportionate to the point units of 72.

If your unit is inch, it would be 1 = 72, but if it's millimeters, it's 1 = 2.83465
