What does one calorie (th)/second represent in SI units?

One calorie (th)/second equals exactly 4.184 watts, as it transfers one thermochemical calorie of energy per second.

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

Converting to calorie (th)/hour allows expressing power in smaller, more granular units suitable for low-rate heat transfer, often used in laboratory and physiological contexts.

Are thermochemical calorie units still commonly used?

They are considered legacy units and have largely been replaced by watts in modern applications, but they persist in some specialized or older engineering literature.
