Unscaled diameter of a circle/sphere with an area/volume equal to that of the object.

The object is measured using the Area Unscaled feature. A circle with the same area as the object is created. The diameter of this circle is returned.
In case of a three dimensional analysis, the equivalent sphere with the Volume Unscaled of the region is measured and the diameter of the sphere is returned.

• Formula 2D: Sqrt ((4/π)*Area Unscaled)
• Formula 3D: Pow(6*Volume Unscaled/π, 1/3)
• Unit: pixels
