Useful Formulas

Below are the formulas and conversion factors I used to write this feature:

	1 in. = 25.4 mm
	1 cu. in. = .0164 liter
	Displacement (cu. in.) = 0.7853982 x bore squared x stroke x number of cylinders
	HP = (RPM x torque) / 5252

Bob Helt recently pointed me to Bruce Bowling's gold mine of online programs for calculating all manner of auto-related figures. Be sure to check out Automotive Calculations by Bowling & Grippo.
