What Is This Tool?
This converter allows you to transform power values measured in joule per second (J/s) into kilocalorie (IT) per hour (kcal/h). Both units describe rates of energy transfer and are commonly used in various fields such as heating, cooking, and metabolic studies.
How to Use This Tool?
-
Enter the power value in joule per second (J/s) in the input field
-
Select the source unit as joule/second (J/s) and the target unit as kilocalorie (IT)/hour (kcal/h)
-
Click the convert button to get the equivalent power value in kcal/h
Key Features
-
Converts joule/second (J/s) to kilocalorie (IT)/hour (kcal/h) effortlessly
-
Browser-based tool with simple, user-friendly interface
-
Useful for HVAC, cooking appliance ratings, and metabolic rate calculations
Examples
-
Convert 2 J/s: 2 × 0.8598452279 = 1.71969 kcal/h
-
Convert 5 J/s: 5 × 0.8598452279 = 4.29923 kcal/h
Common Use Cases
-
Specifying electrical and mechanical power output in various appliances and devices
-
Defining heating or cooling capacity of small heaters, boilers, and radiators
-
Measuring human metabolic heat production and energy-expenditure rates
Tips & Best Practices
-
Ensure correct input units before converting to avoid errors
-
Use the conversion for applications such as HVAC system design, cooking appliance specifications, and metabolic studies
-
Be aware of unit distinctions such as the International Table kilocalorie to maintain accuracy
Limitations

Kilocalorie (IT)/hour is less common globally compared to watts
-
Conversion precision is important to ensure correct results
-
Differences among calorie definitions may affect accuracy if not properly considered
Frequently Asked Questions
-
What does joule per second [J/s] measure?
-
Joule per second is an SI derived unit of power that measures the rate at which energy is transferred, converted, or expended, and it is exactly equal to one watt.
-
Where is kilocalorie (IT)/hour commonly used?
-
Kilocalorie (IT)/hour is commonly used in specifying heating or cooling capacity of small heaters, boilers, and radiators, as well as rating cooking appliances and expressing human metabolic heat production.
-
How do I convert 1 J/s to kcal/h?
-
1 joule per second equals approximately 0.8598452279 kilocalorie (IT) per hour.
Key Terminology
-
Joule per second (J/s)
-
