What is the basic conversion formula between pound-foot per second and horsepower?

One pound-foot per second equals approximately 0.0018181818 horsepower [hp, hp (UK)].

Why should I convert pound-foot per second to horsepower?

Converting these units helps translate mechanical power figures from US customary units into the commonly used horsepower unit, which is essential for automotive and machinery specifications.

Are there different types of horsepower I should be aware of?

Yes, while this converter uses the mechanical/imperial horsepower variant defined as 550 foot-pounds per second, other types like metric horsepower exist and have slightly different values.
