What is the definition of mechanical horsepower?

Mechanical horsepower is an Imperial unit of power defined as 550 foot-pounds per second and approximately 745.7 watts.

How is pound-foot per second defined?

A pound-foot per second measures power as one pound-force foot of work done each second, roughly equal to 1.3558 watts.

Why is this conversion useful for automotive applications?

It translates engine power ratings into mechanical work rates compatible with Imperial units used in vehicle performance and mechanical engineering.
