Kuinka laskea Horsepower Converter

Mikä on Horsepower Converter?

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.

Kaava

1 HP = 745.7 W | HP = Torque(lb-ft) × RPM / 5252

Usein kysytyt kysymykset

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.
