Or if you dont wanna count teeth... Put the car up in neutral (on a lift) and put a mark on the driveshaft and a mark on a rear tire. Turn the rear tire 1 complete turn and count the number of times the driveshaft turned, but it has to be precise... if it goes around 3 and 3/4 times, then its obviously 3.73s... if it goes around 3 1/4 times then its 3.23's... u catch my drift.
