rpm formula

amfet

hi, is it possible to add to the recorded data RPM calculated from the speed (v) using the formula when I enter the number of teeth on the pinion (Tp), rosette (Tr) and wheel circumference (Cw)? At least for orientation.
formula: RPM = (60*v*Tr)/(3,6*Cw*Tp)
[RPM] = 1/min
[v] = km/h
[Cw] = m

At the moment RaceChrono doesn't support general math channels like that, but these are on my TO-DO list.
