What is horsepower (hp, hp UK)?

Horsepower in this context is a non-SI unit of power defined as 550 foot-pounds per second, approximately equal to 745.7 watts, commonly used in automotive and mechanical fields.

What does megajoule per second (MJ/s) represent?

Megajoule per second is a power unit equal to one million joules transferred or converted every second, equivalent to one megawatt, used to quantify large-scale energy delivery.

Why convert horsepower to MJ/s?

Converting horsepower to megajoule/second helps express power in standardized SI units, facilitating comparison with industrial, electrical, and thermal power systems.
