What does megajoule per second measure?

Megajoule per second (MJ/s) measures power as the rate of energy transfer equal to one million joules per second, often used for describing large-scale energy output.

When is femtojoule per second used?

Femtojoule per second (fJ/s) quantifies extremely small power levels, typically applied in nanoelectronics, single-photon detection, and experimental physics requiring very fine energy measurements.

Why convert from MJ/s to fJ/s?

Converting from MJ/s to fJ/s helps bridge power measurement scales from macro-level industrial generation to nano-scale energy transfer in experimental and quantum research.
