Circularity and roundness
WebCircularity or roundness is a form control that may be applied to any feature containing circular slices. The tolerance zone for circularity is the annulus area between two circles with the same center. The width of the zone is the difference between the radii of the two concentric circles. http://www.cyto.purdue.edu/cdroms/micro2/content/education/wirth10.pdf

A common definition used in digital image processing (image analysis) for characterizing 2-D shapes is: Roundness = Perimeter 2 4 π × Area. This ratio will be 1 for a circle and greater than 1 for non-circular shapes. Another definition is the inverse of that: Roundness = 4 π × Area See more Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle.
