What does femtojoule per second represent?

Femtojoule per second (fJ/s) is a power unit indicating an extremely small energy transfer rate, equal to 10⁻¹⁵ joules per second or watts.

In what context is the petawatt unit used?

Petawatt (PW) is used to express very high power levels such as those in petawatt-class lasers, astrophysical events, and fusion experiments.

Why convert between femtojoule/second and petawatt?

This conversion helps compare vastly different power scales, aiding understanding across fields like nanoelectronics and plasma physics.
