P = perimeter, A = area. The sphericity S is the ratio of the perimeter of the equivalent circle, P EQPC, to the real perimeter, P real. The result is a value between 0 and 1. The smaller the value, the more irregular is the shape of the particle. This results from the fact that an irregular shape causes an increase of the perimeter.
