What does one gigawatt-hour represent?

One gigawatt-hour (GW*h) is the energy delivered by sustaining one gigawatt of power for one hour, equal to 3.6 × 10^12 joules.

How is a metric horsepower hour defined?

A metric horsepower hour is the energy produced by maintaining one metric horsepower power (735.49875 watts) for one hour, equivalent to about 2,647,795.5 joules.

Why convert gigawatt-hours to metric horsepower hours?

This conversion helps relate large electrical energy amounts to mechanical engine energy outputs, useful in engine testing, energy audits, and efficiency comparisons.
