What Is This Tool?
This converter helps transform power values from calorie (th)/hour, a unit commonly used in thermal measurements, into erg/second, the CGS unit often used in astrophysics and theoretical physics.
How to Use This Tool?
-
Enter the value in calorie (th)/hour that you want to convert
-
Select calorie (th)/hour as the source unit and erg/second as the target unit
-
Click the convert button to obtain the equivalent erg/second value
-
Review the output which applies the fixed conversion factor of 1 cal (th)/h equals 11622.222222222 erg/s

Common Use Cases
-
Reporting small heat-transfer rates during laboratory calorimetry of chemical reactions
-
Expressing metabolic heat production rates in physiological studies
-
Converting thermal power measurements into CGS units used in astrophysics
-
Interpreting power values in CGS-based theoretical physics and older literature
Tips & Best Practices
-
Ensure units are correctly selected before performing conversions
-
Use this converter when working with small thermal power or astrophysical power in non-SI units
-
Be cautious with large numbers due to the difference in unit scales
-
Remember that watts are the preferred SI unit and may be more suitable for some modern applications
Limitations
-
The calorie (th)/hour is a non-SI unit and less common in modern science
-
Conversion involves very small erg/s values requiring careful numeric handling
-
CGS units like erg/s are less widely used outside astrophysics and specific theoretical fields
Frequently Asked Questions
-
What does calorie (th)/hour measure?
-
It is a unit of power measuring thermal energy transfer rate, defined as one thermochemical calorie delivered per hour.
-
Why use erg/second instead of watts?
-
Erg/second is part of the CGS system and is often used in astrophysics and older theoretical works where SI units are less common.
-
How is the conversion factor between cal (th)/h and erg/s determined?
-
Based on established definitions, 1 cal (th)/h equals 11622.222222222 erg/s as a fixed conversion rate.
Key Terminology
