What Is This Tool?
This converter transforms power values from kilocalorie (IT) per second—a unit commonly used in thermal engineering and metabolic energy analysis—into exawatts, a unit representing extremely large power scales found in planetary and astrophysical contexts.
How to Use This Tool?
-
Enter the power value in kilocalorie (IT)/second
-
Select the target unit as exawatt [EW]
-
Click convert to see the equivalent power in exawatts
-

-
Browser-based and easy to use for rapid calculation
Examples
-
10 kilocalorie (IT)/second equals 4.1868e-14 exawatt [EW]
-
500 kilocalorie (IT)/second equals 2.0934e-12 exawatt [EW]
Common Use Cases
-
Reporting heat transfer rates in older engineering and calorimetry studies
-
Converting metabolic energy rates to watts for biomedical research
-
Analyzing planetary-scale energy flows such as Earth's solar power interception
-
Comparing stellar luminosities and astrophysical peak powers
-
Modeling theoretical exascale fusion or global energy systems
Tips & Best Practices
-
Use this tool to bridge everyday thermal power measurements and extremely large energy scales
-
Verify unit selection carefully to avoid confusion between small and massive power units
-
Consider the practical context since conversion results may be extremely small
-
Apply results mostly in theoretical, astrophysical, or large-scale energy modeling scenarios
Limitations
-
Direct conversions yield very small numerical values due to huge difference in scale
-
The kilocalorie (IT) unit is less common in modern applications and mostly historical or niche
-
Precision can be affected by differences in magnitude and specialized unit definitions
-
Conversion is mainly useful for scaling or theoretical comparisons rather than everyday use
Frequently Asked Questions
-
What does kilocalorie (IT)/second measure?
-
It measures thermal power as the rate of energy transfer of one kilocalorie (International Table) per second.
-
What is an exawatt used to describe?
-
Exawatt (EW) describes extremely large power, such as planetary energy flows or astrophysical phenomena.
-
Why are conversion results from kilocalorie (IT)/s to EW very small?
-
Because kilocalorie (IT)/second measures small-scale power while exawatt represents extraordinarily large power scales.
Key Terminology
-
Kilocalorie (IT)/second
-
A unit of power equal to one kilocalorie (International Table) of energy transferred per second, equivalent to 4186.8 watts.
-
Exawatt [EW]
-
An SI power unit equal to 10^18 watts, commonly used to measure extremely large energy transfer rates in planetary and astrophysical contexts.
