HP to Torque Calculator:
Enter the values of Horse Power (HP) and RPM to determine the value of Torque, T(ft.lb).
HP to Torque Formula:
Horsepower (HP) to torque conversion is the process of calculating the rotational force (torque) a motor generates at a certain speed, based on its power output (HP). This conversion is essential for understanding the performance characteristics of engines, relating their power output to the actual rotational force applied at a given RPM (Revolutions Per Minute).

Torque, T(ft.lb) in pound feet is generated by dividing the product of Horse power (HP) and 5252 by RPM.
HP to Torque, T(ft.lb) = (HP * 5252) / RPM.
T(ft.lb) = Torque in pound feet, ft.lb.
HP = Horse Power,
RPM = rotations per minute.
HP to Torque Calculation:
- A sports car’s engine is tuned to produce 300 HP at 5000 RPM. Calculate the torque generated at this engine speed.
Given: Horsepower (HP) = 300, RPM = 5000.
HP to Torque, T(ft.lb) = (HP * 5252) / RPM.
T(ft.lb) = (300 * 5252) / 5000
T(ft.lb) = 315.12 ft.lb
- An industrial electric motor operates at a speed of 2500 RPM and torque produced by the motor is 315.12 ft.lb. Determine the horse power rated by this motor.
Given: Torque, T(ft.lb) = 315.12 ft.lb , RPM = 2500.
HP to Torque, T(ft.lb) = (HP * 5252) / RPM.
315.12 = (HP * 5252) / 2500
HP = 150.
