The following are the basic formulas for convert from diametral pitch, ciurcular pitch and module pitches.

D = Diametral Pitch C = Circular Pitch M = Module

You Have	You Need	Rule	Formula
Diametral Pitch	Circular Pitch	Divide Pi (3.1416) by the diametral pitch	C = 3.1416 / D
	Module	Divide 25.4 by the diametral pitch	M = 25.4 / D

Circular Pitch	Diametral Pitch	Divide Pi (3.1416) by the circular pitch	D = 3.1416 / C
	Module	Multiply the circular pitch by 8.08505	M = C x 8.08505

Module	Diametral Pitch	Module divided by 25.4	D = 25.40 / M
	Circular Pitch	Module divided by 8.08505	C = M / 8.08505
