How is Vehicle Horsepower Calculated?

[LaLucy]

Horsepower equals torque multiplied by rotational speed. Below is a detailed explanation of horsepower: 1. Detailed calculation formula: Power (W) = 2π × Torque (N-m) × Rotational Speed (rpm)/60. After simplification, it becomes: Power (kW) = Torque (N-m) × Rotational Speed (rpm)/9549. This is how a car's horsepower is calculated. Engine horsepower refers to the engine's output capability (work done), i.e., output power. 2. Overview of output power: For other electrical appliances, the nominal power, also called nominal output power, refers to the maximum output power that the appliance can sustain for a long time without distortion. The maximum power refers to the instantaneous peak power that the appliance can handle without damage, representing its maximum load capacity. Output power = Input power – Power loss.
