How to Use the Calculator

  1. Enter the number of teeth of the gear in the "Number of Teeth" field.
  2. Enter the module of the gear in the "Module (mm)" field.
  3. Click the "Calculate" button to calculate the pitch diameter.
  4. The pitch diameter will be displayed in the "Pitch Diameter (mm)" field.

Understanding the Formula

The pitch diameter (D) of a gear is calculated by multiplying the number of teeth (Z) by the module (m). The formula is:

D = Z × m

Where:

  • D = Pitch Diameter (mm)
  • Z = Number of Teeth
  • m = Module (mm)
