Get Price2010-6-28 · So if you set circular pitch to 24px in the gear tool as done above, that rounds to 0.267 inches (24/90 = 0.2666…). Since diametral pitch (P) = Ï€ circular pitch (p), the diametral pitch (P) in inches is = Ï€ 0.267 = 11.781. You will not find any off the shelf gears with a diametral pitch of 11.781.
