What Is This Tool?
This tool converts power units from calorie (IT) per second, a thermal power measure based on the historical International Table calorie, to microwatt, a unit used for very small power values in scientific and engineering contexts.

Key Features
-
Converts historical thermal power units to SI-compatible microwatt values
-
Supports translation of heat-transfer rates from calorie-based units
-
Easy input and instant conversion results
-
Browser-based and accessible without installation
Examples
-
2 calorie (IT)/second [cal/s] equals 8,373,600 microwatt [µW]
-
0.5 calorie (IT)/second [cal/s] equals 2,093,400 microwatt [µW]
Common Use Cases
-
Expressing heat-transfer rates in laboratory calorimetry using the International Table calorie
-
Describing heating or cooling capacities in older technical systems employing calorie units
-
Converting historical thermal power values into SI units during engineering analysis
-
Measuring very small power levels in microelectronics and biomedical devices
Tips & Best Practices
-
Verify unit consistency especially when working with historical data
-
Manage large numerical values carefully when converting from calories per second to microwatts
-
Use this tool to bridge older thermal power units with modern electrical power measurements
Limitations
-
Calorie (IT)/second is an outdated, non-SI unit requiring careful interpretation
-
Converted microwatt values can become very large, so numerical scaling must be handled properly
Frequently Asked Questions
-
What does calorie (IT)/second measure?
-
It measures thermal power as the rate of energy transfer of one International Table calorie per second.
-
Why convert calorie (IT)/second to microwatt?
-
To express thermal power values originally in calorie units into small power units compatible with modern scientific and engineering contexts.
-
Is calorie (IT)/second still a commonly used unit?
-
No, it is largely outdated and mostly found in older literature or specific historical applications.
Key Terminology
-
Calorie (IT)/second [cal/s]
-
A unit measuring power as the rate of energy transfer of one International Table calorie per second, used mainly for thermal power.
-
Microwatt [µW]
-
A unit of power equal to one millionth of a watt, applicable for quantifying very small energy transfer rates.
