Calculating Sprocket Pitch Diameter

When working with synchronous sprockets you'll need to know about pitch diameter.
In the image below you can see that the pitch diameter on a sprocket is an invisible dimension that represents where the pitch line of the belt would be if it was wrapped around the sprocket. Calculating pitch diameter is simple. 

Pitch Diameter = (Belt/Sprocket Pitch) * (# of sprocket grooves) / π
