Examples
-
Convert 10 cal/h: 10 cal/h × 0.01163 = 0.1163 dW.
-
Convert 50 cal/h: 50 cal/h × 0.01163 = 0.5815 dW.
Common Use Cases
-
Reporting small heat-transfer rates in lab calorimetry and thermal tests.
-
Interpreting historical thermal data that use calorie-based power units.
-
Specifying low-power output of electronic devices like sensors and indicator LEDs.
-
Estimating heat losses in insulated components for engineering analysis.
-
Managing power ratings in IoT devices and small amplifiers.
Tips & Best Practices
-
Check unit definitions carefully to ensure correct conversion context.
-
Use this conversion when dealing with very small power values to maintain clarity.
-
Combine calorimetric and electrical power data using this standardized metric conversion.
-
Avoid relying on calorie (IT)/hour units in modern measurements when possible.
-
Use the deciwatt unit for expressing power near one-tenth of a watt for cleaner numeric representation.
Limitations
-
Calorie (IT)/hour is a non-SI and historically defined unit with limited precision.
-
Deciwatt is less common than related units like watts or milliwatts, restricting widespread use.
-
Care needed when interpreting older literature using calorie-based power units.
-
Conversion accuracy depends on adherence to the defined formula and context.
-
Not suitable for expressing larger power levels where standard SI units are preferable.
Frequently Asked Questions
-
What does one calorie (IT) per hour represent?
-
It measures the rate of energy transfer equivalent to one International Table calorie transferred every hour, used mainly for small heat flow rates.
-
Why use deciwatt instead of watts or milliwatts?
-
Deciwatt offers a convenient metric scale for expressing low power levels around one-tenth of a watt, especially suitable for small electronic components.
-
Can I use this conversion for large power values?
-
This conversion is intended for very small power measurements; for larger values, standard units like watts are recommended.
Key Terminology
-
Calorie (IT)/hour [cal/h]
-
A unit of power measuring the rate of energy transfer equal to one International Table calorie per hour, used for small steady heat flow rates.
-
Deciwatt [dW]
-
A metric unit of power equal to one tenth of a watt, commonly used to express low power levels in science and engineering.
-
Power
-
The rate at which energy is transferred or converted, typically measured in watts or related units.
