What is a gigawatt used for?

A gigawatt represents one billion watts of power and is used to express large-scale power production such as electrical output from power plants or national energy capacity.

Why are converted values often very small?

Because one Btu (th)/hour equals a very small fraction of a gigawatt, resulting conversions yield tiny decimal numbers, reflecting the scale difference between the units.
