Examples
-
10 kcal/h converts to 2.779636711 cal(th)/s by multiplying 10 by 0.2779636711.
-
5 kcal/h converts to 1.389818356 cal(th)/s by multiplying 5 by 0.2779636711.
Common Use Cases
-
Determining heating or cooling capacity of small heaters and radiators in HVAC applications.
-
Rating power output of cooking appliances and gas burners using kilocalories per hour.
-
Expressing human metabolic heat production rates reported in kilocalories per hour.
-
Measuring heat flow in laboratory calorimetry experiments.
-
Converting legacy thermal power values into SI units for engineering analysis.
Tips & Best Practices
-
Always ensure input values represent steady-state power for accurate conversion.
-
Acknowledge the difference between International-Table and thermochemical calorie definitions.
-
Use converted values for comparative analysis or compatibility between different unit standards.
-
Consult original equipment documentation when precision is critical due to rounding differences.
Limitations
-
The conversion involves different definitions for International-Table and thermochemical calories.
-
It assumes steady-state conditions and does not account for thermal dynamics or losses.
-
Older sources or instruments may have rounding errors affecting conversion accuracy.
Frequently Asked Questions
-
What is a kilocalorie (IT)/hour used for?
-
It is used to specify small heating or cooling capacities in HVAC systems, rate outputs of cooking appliances, and human metabolic heat production rates.
-
How does a calorie (th)/second differ from a kilocalorie (IT)/hour?
-
A calorie (th)/second measures the transfer of one thermochemical calorie per second, whereas a kilocalorie (IT)/hour measures the transfer of one International-Table kilocalorie per hour, with differing energy definitions.
-
Why convert from kilocalorie (IT)/hour to calorie (th)/second?
-
Conversion allows compatibility across different thermal power units, facilitating detailed laboratory measurements and integration with SI standards.
Key Terminology
-
Kilocalorie (IT)/hour
-
A power unit equal to one International-Table kilocalorie delivered each hour, used in heating and metabolic contexts.
-
Calorie (th)/second
-
A power unit denoting the transfer of one thermochemical calorie each second, often used in calorimetry and older heat power measurements.
-
International-Table Kilocalorie
-
A calorie unit defined as 4,186.8 joules, distinguished from the thermochemical calorie.
