Key Features
-
Converts between kilojoule/hour and kilocalorie (th)/minute units of power.
-
Includes defined units based on energy transfer rates over specific time intervals.
-
Suitable for applications in building physics, physiology, and laboratory calorimetry.
-
Displays results using a fixed conversion factor derived from SI unit relations.
-
Offers example conversions to illustrate the process clearly.
Examples
-
10 kJ/h converts to approximately 0.0398 kilocalorie (th)/minute using the conversion factor.
-
50 kJ/h converts to approximately 0.1992 kilocalorie (th)/minute by multiplying with the rate.
-
Multiply any kilojoule/hour value by 0.0039834289 to obtain kilocalorie (th)/minute.
Common Use Cases
-
Expressing small heating or cooling rates in building physics such as heat loss.
-
Measuring metabolic energy expenditure during exercise in units per time.
-
Conducting calorimetry experiments requiring energy flow measurements over time.
-
Rating the heat output of small thermal devices like burners or grills.
-
Performing food energy transfer calculations in thermal contexts.
Tips & Best Practices
-
Use kilojoule/hour units for energy rates over longer hourly intervals.
-
Apply kilocalorie (th)/minute when thermal energy transfer per minute is relevant.
-
Cross-check results with examples to ensure conversion accuracy.
-
Consider the context of thermal versus nutritional calorie definitions.
-
Be mindful of rounding and time base differences in conversions.
Limitations
-
Kilojoule/hour is less suitable for rapid or high power energy changes.
-
Kilocalorie (th)/minute refers to thermochemical calories, differing from nutritional definitions.
-
Conversion precision may be affected by rounding and differing time intervals.
Frequently Asked Questions
-
What does kilojoule/hour measure?
-
Kilojoule/hour measures power as the rate of energy transfer, specifically 1000 joules delivered or consumed every hour.
-
How is kilocalorie (th)/minute defined?
-
It is a unit of power representing the transfer of one thermochemical kilocalorie per minute, mainly used in thermal energy contexts.
-
Why convert kilojoule/hour to kilocalorie (th)/minute?
-
To express and compare thermal power rates across different time and energy units, especially in physiology, calorimetry, and heating applications.
Key Terminology
-
Kilojoule/hour (kJ/h)
-
A power unit measuring energy transfer of 1000 joules per hour, used for small to moderate rates over hourly periods.
-
Kilocalorie (th)/minute
-
A power unit measuring thermal energy flow as one thermochemical kilocalorie transferred every minute.
-
Power
-
The rate at which energy is transferred, converted, or used per unit time.
