Engineering Calculators
Horsepower Calculator
Calculate HP from torque and RPM; convert between HP, kW, PS.
What is the Horsepower Calculator & How does it work?
Horsepower (HP) is a unit of power commonly used to measure the output of engines. It can be calculated using the formula HP = Torque (Nm) × RPM / 5252, where RPM stands for revolutions per minute.
This calculator also facilitates conversions between different units of power, including kilowatts (kW) and metric horsepower (PS). Understanding these relationships is crucial for engineers and mechanics to optimize engine performance and efficiency. For instance, 1 HP is equivalent to approximately 0.7457 kW or 0.981 PS.
HP = \frac{Torque (Nm) × RPM}{5252}
HP = Horsepower, Torque = Torque in Newton-meters, RPM = Revolutions per minute
