This online calculator is designed to calculate pitch diameter with the well-known number of teeth and diametral pitch.

The formula for calculating pitch diameter with the well-known number of teeth and diametral pitch is presented below:

where D - pitch diameter,
         N - number of teeth,
         P -  diametral pitch.
