Hi all..(adsbygoogle = window.adsbygoogle || []).push({});

I've been seeing the famous equation which 'converts' horsepower into torque: HP = Torque (lb/ft) * rpm / 5252. The 1/5252 comes from 2*PI/33,000.

Power (rotational) is simply torque * angular velocity, isn't it? When I try to plot the imperial version, I get the typical graph with HP and torque intersecting at 5252rpm. But when I try to plot the same torque values in metric using Power (kW) = Torque (Nm) * rpm * 2*PI/60, I get something wayy different with the power and torque curves not even intersecting.

Am I missing out on something? =/
