What is BHP, PS & NM in automobile?
How do you calculate these values?
Brake horsepower is calculated using a dynamometer. Metric horsepower is calculated using the formula PS = (D × n) ÷ 75, where D is the engine's displacement in liters and n is its speed in rpm. Newton-meters of torque is calculated by multiplying the force applied by the distance from the axis of rotation.
