Thot = Tcold + (K x ((Rhot - Rcold) / Rcold))

where K = 256.4 for copper
Thot = hot temperature in deg.C
Tcold = cold temperature in deg.C
Rhot = resistance at hot temperature in ohms
Rcold = resistance at cold temperature in ohms

Having a tachometer would be nice too. No sense in spending thousands of $$ on an EV conversion and not wiring up a tach.
