Well obviously. You just re-arrange the formula.......Not exactly rocket science!!
But what I was saying that on rolling roads and dynos etc they calculate the HP from the torque figure not the other way round.

So keeping Jeff happy (HPx5252)/RPM = Torque. All I'm saying is that in practical applications Matt's formula is used
Incidentally for that equation what would the units of torque be? Pounds/foot? Surely it would be easier to use the simpler metric equation using NM and KW and negating the need for the 5252 division
