RPM's to Gear Ratio

I was wondering if any one knows a site that has a RPM to Gear Ratio Conversion Table. What it does is it shows you if ur driving at 60mph and your RPM is at 2500 then you have 3.55's in the rear (i know thats not right just using it as an example)

If anyone knows the site can you please email me the link and put GEAR RATIO TABLE in the subject...otherwise post the link in this thread.

Thanks to whoever finds this........
