What is a gigawatt-hour?

A gigawatt-hour (GW*h) is a measure of energy representing one gigawatt of power delivered continuously for one hour, equivalent to 3.6 × 10¹² joules.

Why convert gigawatt-hours to watt-seconds?

Converting to watt-seconds allows expressing large energy amounts in fundamental SI units for fine-grained scientific or engineering calculations involving shorter time intervals.

Are watt-seconds commonly used for large-scale energy reporting?

No, watt-seconds are usually used for short-duration or impulse energy events and are less suitable for communicating large-scale energy consumption in routine reporting.
