I'm pretty sure these are the correct formulae

A= RPM
B= MPH
C= Overall Gear Ratio
D= Tire Height


A= B x C x 345
-----------
D

B= A x D
-----
C x 345


Cant remember what site I got these from. The only thing questionable is the 345 constant. Not sure if that's correct or not. Someone correct me if I'm wrong

From looking at that calculator the constant is 336 not 345 <img src="images/icons/smile.gif" border="0"> but everything else should be correct
