What does one picojoule per second represent?

One picojoule per second represents a power level of 10⁻¹² watts, commonly used to describe very small continuous power in microelectronics and photonics.

Why convert from pJ/s to calorie (th)/hour?

Converting from pJ/s to calorie (th)/hour helps translate electrical or optical power into thermal power units used in calorimetry, physiology, and heat transfer studies.

Are calorie (th)/hour units commonly used in science?

Calorie (th)/hour units are less common than watts because they are non-SI, but they remain important in specific applications like laboratory calorimetry and physiological heat measurement.
