What Is This Tool?
This converter helps transform power values expressed in joules per hour, which represent very low rates of energy transfer, into calories (thermochemical) per minute, a unit often used in calorimetry and metabolic rate assessments.
How to Use This Tool?
-
Enter the power value in joule/hour [J/h] into the input field.

Key Features
-
Converts power from joule/hour [J/h] to calorie (th)/minute accurately based on defined conversion rates.
-
Supports analysis of very low continuous energy transfer rates.
-
Useful in laboratory calorimetry, physiological energy expenditure, and food science heat transfer.
-
Browser-based and easy to use without requiring additional software.
-
Includes example conversions for quick reference.
Examples
-
10 joule/hour converts to 0.039834289 calorie (th)/minute.
-
100 joule/hour converts to 0.39834289 calorie (th)/minute.
Common Use Cases
-
Expressing very low continuous power or standby energy losses in small electronics over hours.
-
Converting long-duration energy measurements into instantaneous power rates for engineering.
-
Characterizing slow thermal loss or heat outputs in laboratory experiments.
-
Reporting heat release rates in small-scale calorimetry studies.
-
Expressing metabolic energy expenditure in physiology research.
-
Evaluating heat transfer in food science and product heating tests.
Tips & Best Practices
-
Ensure accurate input values reflecting energy transferred over correct periods.
-
Use consistent units and be mindful of the specific thermochemical calorie definition.
-
Apply this conversion primarily for low power or slow energy transfer contexts.
-
Cross-check results when dealing with different definitions of calorie units.
Limitations
-
Joule per hour represents extremely low power so the conversion may not suit high-power applications.
-
Calorie (th)/minute strictly uses thermochemical calorie; other calorie units differ and are incompatible here.
-
Accurate results depend on precise measurement of energy and timing over extended durations.
Frequently Asked Questions
-
What does joule/hour [J/h] measure?
-
Joule/hour measures power as the amount of energy transferred per hour, representing slow or very low power transfer rates.
-
Why convert joule/hour to calorie (th)/minute?
-
Converting to calorie (th)/minute provides a useful unit for metabolic studies, calorimetry, and thermal energy transfer calculations common in laboratory and food science settings.
-
Can this converter be used for high-power systems?
-
No, since joule/hour indicates very low power levels, this converter is less practical for high-power or instantaneous energy transfer scenarios.
Key Terminology
-
Joule/hour [J/h]
-
A unit of power quantifying one joule of energy transferred or converted per hour, used to express very low power rates.
-
Calorie (th)/minute
-
A power unit representing one thermochemical calorie (4.184 joules) transferred per minute, often used in calorimetry and metabolic rate measurements.
-
Power
-
The rate at which energy is transferred or converted, measured in units such as watts, joule/hour, or calorie per minute.
