What Is This Tool?
This tool helps convert power measurements specifically from calorie (IT)/second, a unit based on the International Table calorie, to kilocalorie (th)/hour, which uses the thermochemical kilocalorie. It simplifies the process of translating heat energy rates between these two related units used in thermal and HVAC applications.

Common Use Cases
-
Translating heat-transfer rates from International Table calorie system to thermochemical kilocalorie units
-
HVAC system design and analysis involving heat output and thermal loads
-
Laboratory calorimetry data interpretation and conversion for engineering purposes
-
Comparing heating and cooling capacities of various appliances and equipment using legacy units
Tips & Best Practices
-
Always ensure you know which calorie definition your data uses for accurate conversion
-
Use this conversion for steady energy transfer rates rather than variable or transient conditions
-
Interpret converted values carefully, especially when legacy units are involved alongside modern SI units
-
Cross-check your results if precise engineering calculations are needed, considering possible small discrepancies
Limitations
-
Slight differences exist due to varying calorie definitions (International Table vs. thermochemical)
-
Model assumes constant energy transfer and does not cover dynamic thermal changes
-
Legacy calorie units may have less precision compared to contemporary SI measurements
-
Use with caution in critical engineering contexts where exact precision is required
Frequently Asked Questions
-
What does 1 calorie (IT)/second represent?
-
It is a unit of power that quantifies the rate of energy transfer of one International Table calorie per second, often used in thermal power and heat-transfer rate measurements.
-
Why convert calorie (IT)/second to kilocalorie (th)/hour?
-
This conversion enables translating heat-transfer rates from the International Table calorie system to the thermochemical kilocalorie system, prevalent in practical HVAC, laboratory, and appliance applications focused on hourly heat flow.
-
Are there any differences between these calorie units?
-
Yes, the International Table calorie and thermochemical kilocalorie have slightly different definitions, which can cause minor discrepancies in conversions.
Key Terminology
-
Calorie (IT)/second [cal/s]
-
A unit of power representing the rate of energy transfer of one International Table calorie per second, used mainly to express thermal power in heat-transfer contexts.
-
Kilocalorie (th)/hour
-
A power unit defining energy transferred as one thermochemical kilocalorie per hour, commonly used to rate heat flow in HVAC and appliance applications.
-
Heat-transfer rate
-
The amount of heat energy transferred per unit time, often expressed in units like calorie (IT)/second or kilocalorie (th)/hour.
