What Is This Tool?
This tool converts power values from calorie (IT)/second, a unit representing heat energy transfer rate using International Table calories, to kilocalorie (th)/minute, which measures thermal energy transfer using thermochemical kilocalories per minute. It helps translate historical and physiological thermal power data into comparable units.

Frequently Asked Questions
-
What does calorie (IT)/second measure?
-
It measures power as the rate of energy transfer using the International Table calorie per second, representing heat-transfer rates.
-
Why convert to kilocalorie (th)/minute?
-
Kilocalorie (th)/minute is useful in physiology and thermal engineering contexts where energy transfer is expressed per minute using thermochemical kilocalories.
-
Is this conversion commonly used in modern engineering?
-
This conversion is less common in modern SI-based units but remains important for analyzing historical data and specific interdisciplinary applications.
Key Terminology
-
Calorie (IT)/second [cal/s]
-
A unit of power representing heat energy transfer rate using one International Table calorie per second.
-
Kilocalorie (th)/minute
-
A power unit measuring thermal energy transfer equal to one thermochemical kilocalorie delivered per minute.
-
Thermochemical kilocalorie
-
A calorie unit based on the thermochemical definition, differing slightly in energy value from the International Table calorie.
