What is an erg/second?

An erg per second is the CGS system unit of power, representing energy transferred at one erg per second, where 1 erg equals 1 g·cm²·s⁻².

Why convert erg/second to watt?

Converting erg/second to watt allows expression of power in the SI system, facilitating standardization and practical application in physics and engineering.

Where is erg/second commonly used?

Erg/second is often used in astrophysics for luminosity measurements and in older scientific literature and theoretical CGS-based calculations.

What Is This Tool?

This converter allows you to transform power measurements from erg/second, a CGS unit, into watts, the SI unit of power. It is especially useful for interpreting data in astrophysics and theoretical physics using standardized units.

How to Use This Tool?

Input the numerical power value in erg/second (erg/s)
Select erg/second as the source unit and watt (W) as the target unit
Click convert to see the equivalent power value in watts
Use the converted watt value for further calculations or reporting

Key Features

Converts power from erg/second (erg/s) to watt (W) using the precise factor of 1 erg/s = 1e-7 W
Supports astrophysical and theoretical physics calculations requiring unit compatibility
Browser-based and simple to operate with instant results
Helps translate CGS-based power values into the widely adopted SI system

Examples

Convert 5000 erg/s to watt: 5000 × 1e-7 W = 0.0005 W
Convert 1,000,000 erg/s to watt: 1,000,000 × 1e-7 W = 0.1 W

Common Use Cases

Expressing luminosities and the radiative power of astronomical bodies
Reporting power values in theoretical physics that use CGS units
Ensuring compatibility with SI units for engineering and scientific communication

Tips & Best Practices

Always verify source units to ensure accurate conversion
Use sufficient numeric precision due to the small scale of erg/second values in watts
Confirm the context of power values, especially with older literature or CGS-based calculations

Limitations

Erg/second is mainly used within CGS frameworks and older scientific texts
Converted watt values may be very small, requiring careful measurement and reporting
Not suitable for direct use in contexts outside CGS or astrophysical applications without verification
