What does one horsepower (metric) hour represent?

It is the energy delivered by maintaining one metric horsepower for one hour, equivalent to about 735.49875 watt-hours.

Why convert horsepower hours to watt-hours?

Converting to watt-hours allows comparison between mechanical engine energy and electrical energy units used in billing, battery capacity, and energy audits.

Can I use watt-hours directly for engine performance?

Watt-hours are primarily for electrical energy; mechanical engine energy is better expressed in horsepower hours, but conversion helps relate the two.
