What is an erg per second (erg/s)?

An erg per second is a CGS unit of power equal to one erg of energy transferred each second, where one erg corresponds to a small amount of energy.

How many kilowatts are in one erg per second?

One erg per second is equal to 1e-10 kilowatts (kW).

In what fields is converting erg/s to kW commonly used?

This conversion is commonly applied in astrophysics for radiative power and in engineering or household energy settings where kilowatts are standard.

What Is This Tool?

This unit converter allows you to transform power measurements expressed in erg per second (erg/s), a CGS unit, into kilowatts (kW), a widely used SI unit of power. It supports converting astrophysical or older scientific data into practical engineering units.

How to Use This Tool?

Enter the power value in erg/second you want to convert.
Select erg/second as the input unit and kilowatt as the output unit.
Click convert to see the equivalent power in kilowatts.
Use the results for interpreting power measurements across different fields.

Key Features

Converts erg/second (erg/s), a CGS power unit, to kilowatt (kW), an SI power unit.
Includes precise conversion based on established unit relationships.
Supports applications in astrophysics, electrical engineering, and household energy analysis.
Browser-based tool with a straightforward interface for quick conversions.

Examples

10,000 erg/s equals 0.0000001 kW.
5,000,000 erg/s converts to 0.0005 kW.

Common Use Cases

Expressing luminosities and radiative power in astrophysical research.
Translating power values from CGS-based older scientific literature into SI units.
Rating electrical appliances and evaluating household power consumption.
Specifying power output in generators, motors, and renewable energy equipment.

Tips & Best Practices

Remember that erg/second is a very small unit compared to kilowatt, so expect small decimal conversions.
Use scientific notation or precision settings to handle tiny decimal results effectively.
Verify unit selections carefully to ensure accurate conversions between CGS and SI systems.
Leverage this tool mainly for scientific, astrophysical, or specialized power measurement contexts.

Limitations

Converted values often yield very small decimals due to the difference in unit scales.
Erg/second is rarely used in contemporary practical engineering, mostly appearing in specialized literature.
Direct conversions serve compatibility purposes rather than routine engineering measurement.
