Utilize our free online Horsepower Calculator to quickly determine your engine's horsepower (HP) output. Simply input your engine's torque in lb-ft and its corresponding revolutions per minute (RPM), and get instant, accurate results. Perfect for automotive enthusiasts, engineers, and mechanics seeking precise power metrics.
Formula:
Horsepower (HP) = (Torque (lb-ft) × RPM) / 5252
Where:
- Torque: Rotational force in pound-feet (lb-ft).
- RPM: Engine speed in revolutions per minute.
- 5252: A constant used for unit conversion, derived from (33,000 ft·lb/min / 2π radians/revolution).
