Horsepower (hp) is a unit of power originally defined by James Watt to compare steam engine output to horse work. One mechanical horsepower = 745.7 watts. Metric horsepower (CV/PS) = 735.5 watts.

- 11 HP (mechanical) = 745.7 W
- 21 CV/PS (metric) = 735.5 W
- 3Power (W) = Torque (N·m) × Angular velocity (rad/s)
- 4kW = HP × 0.7457; HP = kW × 1.341

Why is it called "horsepower"?
James Watt coined the term by measuring how much work a horse could do. One horse could lift 550 pounds 1 foot in 1 second — that became the standard.
Is horsepower the same as torque?
No. Torque is rotational force. Horsepower is the rate at which work is done. A given torque at higher RPM produces more horsepower.
Why do cars list both torque and horsepower?
Torque determines acceleration at a given RPM. Horsepower determines top speed. Both matter for understanding engine performance.
