A Simpler Explanation Of The Measurement Of ONE HORSE POWER
One horsepower equals 550 foot pounds (pound feet) per second. In high school, in physics class, I generated 1 horsepower by running up a flight of stairs. :) Housted

I'm NOT trying to start once again that infamous RV/truck owners' timeless discussion ... BUT: Isn't all horsepower the same? And also don't modern rotating machines merely convert their available horsepower into the required rotating torque at the required location using various gears and driveshafts?
Now here's what I'd sure like to have explained ... why a 300 horsepower diesel RV engine can "tow better" than a 300 hrosepower gas RV engine? That has never made sense to me. :h
Horsepower doesn't convert to torque nor vice versa. Torque is constant over the RPM range, while Horsepower is a straight line function of RPM. Thus, the diesel engine, which operates with a typical limit of 2400 RPM produces more torque than a typical gas engine which operates up to 5500 RPM. Another factor that produces torque is larger displacement (BIG pistons)
