What Is This Tool?
This converter helps you translate power measurements from exajoule per second (EJ/s), a very large SI-based unit, to erg per second (erg/s), a CGS-system unit commonly used in astrophysics and older scientific literature.
How to Use This Tool?
-
Enter the power value in exajoule per second (EJ/s) you want to convert.
-
Select erg per second (erg/s) as the target unit.
-
Click the convert button to get the equivalent power in erg per second.
-
Review the displayed result and use it for your scientific or technical needs.
Key Features
-

Examples
-
2 EJ/s converts to 2 × 10^25 erg/s or 20000000000000000000000000 erg/s.
-
0.5 EJ/s converts to 0.5 × 10^25 erg/s or 5000000000000000000000000 erg/s.
Common Use Cases
-
Analyzing the luminosities of stars like the Sun.
-
Evaluating energy budgets of planets such as Earth's solar absorption.
-
Reporting radiative power in astrophysical research involving black holes and X-ray binaries.
-
Converting power values to compatible units for theoretical physics and older scientific literature.
Tips & Best Practices
-
Ensure you understand which unit system (SI or CGS) fits your scientific context.
-
Use this tool for large-scale energy calculations typical in astrophysics or planetary science.
-
Be cautious when converting extremely large numbers to avoid loss of precision.
-
Verify results when switching between unfamiliar units to prevent confusion.
Limitations
-
Exajoule/second units represent extremely large power, limiting use to planetary or astrophysical scales.
-
Erg/second may be less intuitive for users accustomed to SI units, which can cause misunderstanding.
-
Numerical precision might decrease with converting very large or very small quantities.
