What Is This Tool?
This tool allows users to convert power measurements from microjoule per second (µJ/s), a unit representing very small power levels mostly used in electronics and optics, to erg per second (erg/s), the CGS-system unit often found in astrophysics and older scientific works.
How to Use This Tool?
-
Enter the value in microjoule/second (µJ/s) you want to convert
-
Select microjoule/second as the input unit and erg/second as the output unit
-
Click the convert button to get the equivalent value in erg/second
-
Review the results and use them for your scientific or engineering needs
Key Features
-
Converts microjoule/second (µJ/s) to erg/second (erg/s) accurately
-
Provides a clear conversion formula and example values
-
Web-based and easy to use without installation
-
Supports understanding of unit applications in different scientific fields
Examples
-
2 µJ/s converts to 20 erg/s
-
0.5 µJ/s equals 5 erg/s
Common Use Cases
-
Expressing very small power levels in the CGS unit system for astrophysical data
-
Converting power units in theoretical physics where the CGS system is preferred
-
Describing power consumption of ultra-low-power devices in compatible units
-
Reporting radiative power in scientific literature that uses erg/second
Tips & Best Practices
-
Ensure consistent use of units across your dataset to avoid errors
-
Use this conversion tool when working with CGS unit–based calculations or legacy data
-
Verify the unit definitions match your application context before conversion
-
Refer to examples to confirm your conversion results
Limitations
-
Erg per second is less common in modern engineering which mainly uses SI units
-
Mixing CGS and SI units without care can lead to errors in calculations
-
This tool does not provide conversion beyond the specified units between microjoule/second and erg/second
Frequently Asked Questions
-
What does microjoule/second measure?
-
Microjoule per second (µJ/s) measures very small continuous power levels, such as in low-power electronics and optical systems.
-
Why convert µJ/s to erg/s?
-
Conversion to erg/second is useful for expressing small power in the CGS system, often required in astrophysics and theoretical physics.
-
What is the conversion rate between µJ/s and erg/s?
-
1 Microjoule per second equals 10 erg per second according to the established conversion formula.
Key Terminology
-
Microjoule/second (µJ/s)
-
A unit of power indicating the transfer of one microjoule of energy every second, equal to 10⁻⁶ watts.
-
Erg/second (erg/s)
-
The CGS-unit of power representing one erg of energy transferred per second, equivalent to 1×10⁻⁷ watts.
-
Power
-
The rate at which energy is transferred or converted, measured in watts in SI units or erg/s in the CGS system.
