-
Evaluating small indicator LEDs and status light outputs
-
Translating micro-energy harvesting outputs into thermal units
-
Reporting heat flow rates in laboratory calorimetry experiments
-

Tips & Best Practices
-
Ensure you understand the unit contexts before converting
-
Maintain the fixed thermochemical calorie definition at 4.184 joules
-
Use precise input values to avoid inaccuracies due to small magnitudes
-
Be aware calorie (th)/second is less common in modern electrical power use
-
Cross-check conversions when applying to critical scientific or engineering calculations
Limitations
-
Calorie (th)/second is a non-SI unit and may not be widely accepted in all contexts
-
Conversion relies on the fixed value of the thermochemical calorie as exactly 4.184 joules
-
Small values in centiwatt result in very small output numbers, requiring careful precision
-
May not be suitable for high-power or non-thermal power applications
Frequently Asked Questions
-
What is a centiwatt?
-
A centiwatt (cW) is a power unit equal to one hundredth of a watt, typically used for very low power levels such as in small electronics.
-
How is calorie (th)/second defined?
-
Calorie (th)/second is a power unit equal to the transfer of one thermochemical calorie per second, where one thermochemical calorie is exactly 4.184 joules.
-
Why convert centiwatts to calorie (th)/second?
-
Users convert between these units to relate low electrical power measurements to thermal power rates common in calorimetry and historical engineering contexts.
