What Is This Tool?
This converter helps you change power measurements from kilojoule per second, a unit representing energy transfer rate equivalent to 1,000 joules per second, into kilocalorie (thermochemical) per second, a unit often used for thermal power and heat flow rate based on thermochemical calories.
How to Use This Tool?

Key Features
-
Converts power units from kilojoule/second to kilocalorie (th)/second quickly and easily.
-
Suitable for applications in HVAC, thermal engineering, boilers, and calorimetry.
-
Browser-based tool requiring no installation.
-
Supports precise unit conversion with a clear conversion factor.
Examples
-
5 kJ/s converts to approximately 1.195 kilocalorie (th)/second.
-
10 kJ/s converts to roughly 2.39 kilocalorie (th)/second.
Common Use Cases
-
Rating electrical and mechanical power outputs of appliances and motors.
-
Quantifying thermal energy transfer in heating, ventilation, air conditioning, and boilers.
-
Specifying turbine or engine power in industrial and power generation sectors.
-
Reporting heat release rates during calorimetry and thermal testing.
-
Sizing heat exchangers and HVAC systems using calorie-based units.
Tips & Best Practices
-
Ensure units are steady state power values to maintain conversion validity.
-
Use the thermochemical calorie basis when performing heat transfer calculations.
-
Be mindful of unit definitions, especially when comparing with other calorie types.
Limitations
-
Kilocalorie (th)/second is linked specifically to the thermochemical calorie and differs from other calorie definitions.
-
Not suitable for transient or non-uniform heat transfer conditions, as the conversion assumes steady power.
Frequently Asked Questions
-
What does kilojoule per second measure?
-
Kilojoule per second measures power as the rate of energy transfer, equal to 1,000 joules per second, equivalent to one kilowatt.
-
In what contexts is kilocalorie (th)/second used?
-
It is used to quantify thermal power or heat flow rates in heating elements, boilers, calorimetry, and HVAC system design using thermochemical calories.
-
Can I use this conversion for non-steady state power?
-
No, this conversion assumes steady state power and may not be accurate for transient or varying heat transfer scenarios.
