WebJul 7, 2024 · How do you calculate circularity? Calculating Circularity To achieve this, a common measure of circularity is given by four times pi times the area divided by the perimeter squared: C = 4_pi_A/P^2 ~ 12.57_A/P^2, where C is the circularity, A is the area and P is the perimeter. For a circle, C = 1. WebA point, axis, line, or plane consistent with or resulting from processing or inspection table, gage, surface, or a mandrel.
