What does 1 gigawatt equal in milliwatts?

1 gigawatt equals 1,000,000,000,000 milliwatts, converting very large power values into much smaller units.

Why convert gigawatts to milliwatts?

Converting gigawatts to milliwatts helps compare large-scale power generation figures with the power levels used by small electronic devices.

Can this conversion be used for measuring small electronic power directly?

No, due to the hugely different scales, it is mainly useful for analytical purposes and relating power units rather than direct measurement of small devices.
