What is the difference between mechanical horsepower and metric horsepower?

Mechanical horsepower (hp, hp UK) is defined as 550 foot-pounds per second, approximately 745.7 watts, whereas metric horsepower is exactly 735.49875 watts, leading to slight differences in power ratings.

Why convert horsepower [hp, hp (UK)] to metric horsepower?

Converting allows for consistent comparison and specification of power outputs in technical specifications and product datasheets across regions using different horsepower standards.

Are the conversion rates the same for all types of horsepower?

No, the provided conversion rate applies only to the mechanical (imperial) and metric horsepower variants; other types require different conversion factors.

How to Convert from Horsepower [hp, hp (UK)] to Horsepower (metric)?
