What Is This Tool?
This converter allows you to change power measurements from dekajoule per second (daJ/s), an SI-derived unit, to calorie (IT) per hour (cal/h), a unit used mainly for small heat flow rates in thermal testing and calorimetry. It helps bridge modern SI units with historical calorie-based units.
How to Use This Tool?
-
Enter the power value in dekajoule per second (daJ/s)
-
Select dekajoule per second as the input unit and calorie (IT) per hour as the output unit
-
Click the convert button to get the equivalent value in calorie (IT) per hour
-
Use the result for analysis in thermal processes or calorimetric reporting
Key Features
-
Converts from dekajoule per second [daJ/s] to calorie (IT) per hour [cal/h]
-
Based on the exact conversion rate 1 daJ/s = 8598.4522785899 cal/h
-
Supports application in laboratory calorimetry and thermal testing
-
Browser-based and easy to use without installation
-
Useful for translating SI unit measurements to small heat flow rates in calories
Examples
-
2 daJ/s converts to approximately 17196.9 cal/h
-
0.5 daJ/s converts to roughly 4299.23 cal/h
Common Use Cases
-
Measuring small heat-transfer rates in laboratory calorimetry
-
Interpreting technical specifications in older literature using calorie units
-
Estimating heat losses or gains in small insulated components
-
Reporting power in thermal and material testing environments
Tips & Best Practices
-
Always confirm the definition of the calorie used is the International Table calorie for consistency
-
Apply this conversion mainly for low power levels to avoid handling very large numbers
-
Ensure measurements represent steady-state conditions for meaningful conversion
-
Use the tool for bridging SI and calorie units in research or engineering contexts
Limitations
-
Calorie (IT)/hour is designed for very small power values and can be impractical for high power
-
Conversion accuracy depends on the calorie definition; this tool uses the International Table calorie
-
Not suitable for transient or dynamic thermal conditions where steady-state assumptions fail
Frequently Asked Questions
-
What is a dekajoule per second?
-
It is an SI-derived power unit equal to 10 joules per second or 10 watts, used to express energy transfer rates.
-
Why use calorie (IT)/hour as a unit of power?
-
It is useful for measuring very small heat flow rates, especially in laboratory calorimetry and thermal testing.
-
Can I convert high power values using this tool?
-
This unit is intended for small power levels; using it for high power results in very large numbers that can be unwieldy.
Key Terminology
-
Dekajoule per Second (daJ/s)
-
An SI-derived unit of power equal to ten joules per second, used to quantify energy transfer rates.
-
Calorie (IT)/Hour (cal/h)
-
A unit of power measuring energy transfer at the rate of one International Table calorie per hour, used for very small heat flows.
