-
Convert 0.5 cW: 0.5 × 8.604206501 = 4.3021032505 cal (th)/h.
Common Use Cases
-
Specifying power consumption of ultra-low power electronics and sensor nodes.
-
Reporting heat transfer rates in laboratory calorimetry experiments.
-
Describing thermal output in physiological or metabolic heat production studies.
-
Evaluating thermal power in micro-energy harvesting and small device heating.
Tips & Best Practices
-
Use this converter for low-power systems where precision in small measurements matters.
-
Confirm unit preferences in your scientific or engineering context, especially regarding non-SI units.
-
Apply the conversion assuming steady-state conditions without transient power changes.
-
Double-check your input values to avoid scaling errors in the results.
Limitations
-
Conversion applies to steady-state power conditions and does not account for transient variations.
-
Calorie (th)/hour is a non-SI unit and may not be preferred in rigorous scientific reporting.
-
Measurement accuracy can be limited at very low power levels due to instrument tolerances.
Frequently Asked Questions
-
What is a centiwatt used for?
-
A centiwatt quantifies very low power levels, commonly used for ultra-low power electronics, sensor nodes, and tiny photovoltaic cells.
-
Why convert centiwatt to calorie (th)/hour?
-
This conversion helps translate electrical power measurements into thermal power units relevant for heat transfer and physiological heat production.
-
Is calorie (th)/hour an SI unit?
-
No, calorie (th)/hour is a non-SI unit; the watt is the preferred SI unit for power.
Key Terminology
-
Centiwatt [cW]
-
A unit of power equal to one hundredth of a watt, used for measuring very low power levels in electronics.
-
Calorie (th)/hour [cal (th)/h]
-
A thermal power unit representing the transfer of one thermochemical calorie of energy per hour.
-
Power
-
