Formula to convert engine RPM in to MPH in different gears?
Since I'm no car expert I don't know the exact formulas which would lead from one to another (simply because I don't know all the in-between steps between gear rotation and wheel rotation)
I could give you the general formula to calculate the speed of a wheel rolling when you know the RPM and the diameter, but I guess that wouldn't be much help either.
I found this online; http://www.bgsoflex.com/rpmmph.html, which, if you can find out how to calculate each term, might help you.
Hope that will work
