+## Circular pitch
+$P_c$ is the arc distance between two adjacent teeth. The pitch diameter is used for calculating the distance between the centers of gears.
+
+Center distance:
+$$c = {d_1 + d_2 \over 2} = {(N_1 + N_2)m \over 2}$$
+
+Diametral pitch:
+$$P = {N \over d}$$
+Where:
+- $N$ is the number of teeth
+
+Module:
+$$m = {d \over N}$$
