What Is This Tool?
This conversion tool helps translate power values measured in centijoule per second (cJ/s), a unit for very small power levels, into kilocalorie (IT) per hour (kcal/h), which is commonly used to express heating or metabolic energy rates. It enables easy comparison and understanding between scientific measurements and practical applications.
How to Use This Tool?
-
Enter the power value in centijoule per second (cJ/s).
-
Select the output unit as kilocalorie (IT) per hour (kcal/h).
-
Click convert to see the equivalent power in kcal/h.
-
Use the conversion rate 1 cJ/s = 0.0085984523 kcal/h for manual calculations.
Key Features
-
Converts power from centijoule per second (cJ/s) to kilocalorie (IT) per hour (kcal/h).
-
Supports units used in scientific, engineering, HVAC, cooking, and metabolic contexts.
-
Includes real-world example conversions for quick reference.
-
Browser-based tool with straightforward input and output interface.
Examples
-
Convert 10 cJ/s: 10 × 0.0085984523 = 0.085984523 kcal/h.
-
Convert 50 cJ/s: 50 × 0.0085984523 = 0.429922615 kcal/h.
Common Use Cases
-
Describing power consumption of low-power sensors and wearable devices.
-
Evaluating heating output of small boilers, heaters, or radiators.
-
Analyzing energy expenditure rates in human metabolic studies.
-
Converting harvested power in micro-energy harvesting prototypes.
Tips & Best Practices
-
Consider the context of very small power levels when interpreting results.
-
Use the conversion tool to avoid manual calculation errors.
-
Be mindful that converting to kcal/h often results in small fractional values.
-
Confirm the unit definitions before applying conversions in technical documents.
Limitations
-
Centijoule/second measures very small powers, while kilocalorie (IT)/hour suits larger heat rates, so converted values tend to be fractional.
-
Measurement precision may affect conversion accuracy.
-
Avoid confusion by understanding each unit’s typical application context.
Frequently Asked Questions
-
What does 1 centijoule/second represent in power terms?
-
1 centijoule/second equals 0.01 watt and indicates a very small steady power level.
-
When would I need to convert cJ/s to kcal/h?
-
When translating small power measurements into heating capacity or metabolic energy rates frequently expressed in kilocalories per hour.
-
Is the conversion between cJ/s and kcal/h exact?
-
The conversion uses a defined rate but results in small fractional values, so careful interpretation is needed depending on measurement context.
Key Terminology
-
Centijoule per second [cJ/s]
-
A unit of power equal to one hundredth of a joule per second, representing very small steady power levels.
-
Kilocalorie (IT) per hour [kcal/h]
-
A power unit denoting the rate of energy transfer as one International Table kilocalorie delivered each hour, often used for heating and metabolic rates.
-
Power
-
The rate at which energy is transferred or converted.
