What Is This Tool?
This unit converter helps you change power measurements from calorie (IT) per hour, commonly used in thermal and calorimetric contexts, to erg per second, a CGS unit often used in astrophysics and older scientific works. It simplifies translating energy transfer rates between these distinct unit systems.
How to Use This Tool?
-
Enter the value in calorie (IT)/hour that you wish to convert
-
Select the target unit as erg/second
-
Click the convert button to see the equivalent power in erg/s
-
Review the result and use it for your specific application
Key Features
-
Converts power units from calorie (IT)/hour to erg/second accurately
-
Supports small and steady heat flow rate measurements
-
Useful for interdisciplinary applications involving thermal labs and astrophysics
-
Browser-based and easy to use
Examples
-
2 cal/h equals 2 times 11630 erg/s, resulting in 23260 erg/s
-
0.5 cal/h converts to 0.5 times 11630 erg/s, which is 5815 erg/s
Common Use Cases
-
Reporting very small heat-transfer rates in laboratory calorimetry
-
Interpreting historical technical literature that uses calorie units instead of SI
-
Estimating heat losses or gains in insulated experimental setups
-
Expressing astrophysical luminosities and radiative power in CGS units
-
Converting between SI-related and CGS-based power values for research
Tips & Best Practices
-
Verify unit selection before converting to avoid errors
-
Use this tool for small power values as calorie (IT)/hour represents very low power levels
-
Be cautious when working across CGS and SI systems to maintain clarity
-
Consult related scientific context when interpreting results from older literature
Limitations
-
Calorie (IT)/hour is a less common unit for power and best suited for small measurements
-
Erg/second belongs to the CGS system, which is largely replaced by SI units
-
Conversions can be confusing without proper understanding of unit systems
Frequently Asked Questions
-
What does 1 calorie (IT)/hour represent in power units?
-
It represents a power equal to one International Table calorie per hour, used to express very small steady heat flow rates.
-
Why convert calorie (IT)/hour to erg/second?
-
To translate thermal power measurements into CGS units commonly used in astrophysics and older scientific literature.
-
Is erg/second still widely used today?
-
Erg/second is mostly found in CGS-based calculations and historical contexts, as SI units have largely replaced CGS.
Key Terminology
-
Calorie (IT)/hour
-
A unit of power measuring the energy transfer rate of one International Table calorie per hour, used for small heat flow rates.
-
Erg/second
-
A CGS unit of power representing one erg of energy transferred per second, commonly used in astrophysical contexts.
-
Power
-
The rate at which energy is transferred or converted per unit time.
