It’s a measure of the work that a horse would average over an 8 hour shift. A horse can do far more at peak capacity, but it can’t sustain that level of effort for very long.
Horsepower was originated because horses were used for mechanical labor (like lifting loads) so if one is attempting to sell an engine to a company using horse’s power to do a job, the appropriate engine could be found or made to replace a team of 4 horses.
