What Is This Tool?
This tool enables the conversion of power units from calorie (thermochemical) per hour to centijoule per second, facilitating the translation of small thermal power measurements into units compatible with SI-derived standards used in scientific and engineering contexts.
How to Use This Tool?
-
Enter the value measured in calorie (th)/hour into the input field.
-
Select calorie (th)/hour as the source unit and centijoule/second as the target unit.
-
Click the convert button to see the equivalent power in centijoule/second.
Key Features
-
Supports conversion of small thermal power units used in laboratory and physiological measurements.
-
Facilitates unit translation for low power electronic and micro-energy harvesting applications.
-
Provides accurate conversion based on established rates between cal (th)/h and cJ/s.
-
Browser-based and easy to use for quick power unit conversions.
Examples
-
5 cal (th)/h converts to 0.581111111 cJ/s by multiplying 5 by 0.1162222222.
-
10 cal (th)/h converts to 1.162222222 cJ/s using the conversion factor.
Common Use Cases
-
Reporting small heat-transfer rates in laboratory calorimetry.
-
Measuring metabolic or physiological heat production rates with calorie-based units.
-
Specifying power consumption of low-power sensors, IoT devices, or wearable electronics.
-
Characterizing energy output from micro-energy harvesters and photodiodes.
Tips & Best Practices
-
Always double-check input values to avoid errors in small power conversions.
-
Use the tool for precise scientific and engineering analyses involving low power levels.
-
Be aware of the unit differences and the fractional nature of watts represented by these units.
-
Apply this conversion when transitioning from older or domain-specific units to SI-compatible ones.
Limitations
-
The units represent very small power quantities requiring careful precision.
-
Centijoule/second, while closer to SI, is still a fractional watt and not universally standard.
-
Rounding errors may occur during extensive or repeated calculations.
Frequently Asked Questions
-
Why convert from calorie (th)/hour to centijoule/second?
-
To translate thermal power measurements from an older or specialized unit to a unit compatible with SI-derived units for scientific and engineering analyses.
-
What fields commonly use this conversion?
-
It is used in laboratory calorimetry, physiological heat production, low power electronics, IoT sensor characterization, and micro-energy harvesting research.
-
Is centijoule/second a standard scientific unit?
-
Centijoule/second represents fractional watts and is useful for very small power levels, though it is not standard across all scientific areas.
Key Terminology
-
calorie (th)/hour
-
A thermal power unit measuring heat transfer rate equal to one thermochemical calorie delivered per hour.
-
centijoule/second
-
A power unit equal to one hundredth of a joule per second, representing a small energy transfer rate.
-
power
-
The rate at which energy is transferred or converted, commonly measured in watts or subunits like cJ/s.
