How to Calculate Horsepower?

[JakeRose]

Methods for calculating horsepower: 1. Imperial horsepower (hp) = Torque (kg-m) × Engine speed (rpm) / 727 2. Metric horsepower (PS) = Torque (kg-m) × Engine speed (rpm) / 716 3. The horsepower of a car refers to the unit of engine power, which represents the engine's ability to perform work per unit of time. The relevant introduction to car horsepower is as follows: Horsepower equals torque multiplied by speed, symbolizing how much air-fuel mixture the engine can intake per unit of time. Therefore, when the throttle is increased and the engine speed gradually rises to the maximum torque point, although the intake volume per cycle has reached its peak, the speed continues to increase, meaning the number of intake cycles also increases. As a result, horsepower can still rise until it reaches the maximum horsepower point.
