What does nanojoule/second represent?

Nanojoule per second (nJ/s) is a power unit equal to one nanowatt, representing extremely small energy transfers per second used in very low power electronics and photonics.

Why convert to calorie (th)/second?

Calorie (th)/second is used in calorimetry and older thermal engineering to express heat flow, so converting from nanojoule/second can help relate electrical power to thermal power in these fields.

Is calorie (th)/second still widely used?

Calorie (th)/second is largely a legacy unit; most modern power measurements use watts, but it remains relevant for certain laboratory and legacy data applications.
