How to convert wheel RPM to engine RPM?

Is it possible to convert wheel RPM to engine RPM using gear ratios and is there any other factors to this?

I think you should be more elaborate. Explain what you’re doing, is it a car, some mechanic system, what is it? What have you tried so far?

I don’t really understand what you’re asking either.

It is a formula one car, I obtained the wheel revolutions per minute (RPM) through the following:

local function rpm(wheel)

return wheel.RotVelocity:Dot(wheel.CFrame.rightVector)*30/math.pi

end

I tried directly dividing/multiplying the wheel RPM with some of the sample gear ratios found here, however all of these returned very small values (nothing above 280RPM). I can’t tell is this because of a wrong approach to the calculation or the gear ratios being too small, couldn’t find much on the devforum about this either.
