What does a nanowatt measure?

A nanowatt is an extremely small SI-derived unit of power equal to 10⁻⁹ watts, used for very low power levels in precise electronic and photonic systems.

Why convert nanowatts to calories (th)/hour?

Converting nanowatts to calorie (th)/hour helps express low electrical power values as thermal power, especially useful in heat transfer studies and metabolic rate measurements.

Is calorie (th)/hour an SI unit?

No, calorie (th)/hour is a non-SI unit used primarily to measure heat transfer rates in thermal contexts and has limited mainstream usage compared to watts.
