What does femtojoule per second measure?

Femtojoule per second is a unit of power representing extremely small rates of energy transfer equal to 10⁻¹⁵ joule per second.

Why convert femtojoule/second to calorie (th)/hour?

Converting to calorie (th)/hour helps express quantum-scale power levels in thermal units used in calorimetry and physiological heat measurements.

Is calorie (th)/hour an SI unit?

No. Calorie (th)/hour is a non-SI unit commonly used in thermal power contexts but often converted to watts for standard scientific use.
