What does 1 joule per second (J/s) represent?

It is the SI derived unit of power, representing the transfer or conversion of one joule of energy per second, equivalent to one watt (W).

When should I use exajoule per second (EJ/s)?

EJ/s is used to measure extremely large energy flows, such as stellar luminosities or planetary energy budgets, beyond typical appliance or engine power levels.

Why is converting from J/s to EJ/s useful?

It facilitates comparing large-scale energy rates on planetary or astrophysical levels with more common power measurements.
