How to Convert Milliwatt to Erg/Second

To convert from Milliwatt (mW) to Erg/Second (erg/s), multiply the value by 10,000.

Formula: erg/s = mW × 10,000

Reverse: mW = erg/s × 0.0001

Step-by-Step Example

Start with your value in Milliwatt. For example: 5 mW
Multiply by the conversion factor: 5 x 10,000
The result is: 50,000 erg/s

About Milliwatt

The milliwatt (mW) is a unit of power. One milliwatt equals 0.001 watts. UnitConvertLab converts it against every other power unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: power calculations, engineering and science, education.

About Erg/Second

The erg/second (erg/s) is a unit of power. One erg/second equals 1.000000 × 10^-7 watts. UnitConvertLab converts it against every other power unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: power calculations, engineering and science, education.
