What does 1 gigawatt represent in terms of watts?

One gigawatt equals one billion watts, which corresponds to a rate of one billion joules transferred every second.

Why use exajoule per second for measuring power?

Exajoule per second is suited for describing extremely large energy rates such as planetary-scale or stellar luminosities, where power levels reach 10^18 joules per second and beyond.

Can I convert from exajoule/second back to gigawatts?

Yes, conversions between these units follow the inverse relation but require careful handling of very large or small numbers expressed in scientific notation.
