Torque to hp Calculator
Measure the torque in pound-feet (lb-ft). Record the engine's rotational speed in revolutions per minute (RPM). Use the formula: Horsepower (HP) = (Torque × RPM) / 5252. Multiply the torque by the RPM. Divide that number by 5252. This formula gives you the horsepower, reflecting the engine's power output.
