What does calorie (th)/second represent?

It is a power unit indicating the transfer of one thermochemical calorie of energy per second, where one thermochemical calorie equals exactly 4.184 joules.

Why use kilocalorie (IT)/second instead of calorie (th)/second?

Kilocalorie (IT)/second is used for reporting larger scale heat-transfer rates often found in older engineering and biomedical literature, providing a convenient unit for higher magnitude thermal power.

Can this tool help with physiological metabolic power analysis?

Yes, it helps convert metabolic energy rates expressed in kilocalories per hour to units aligned with watts, facilitating physiological or biomedical computations.
