How to Convert Watt to Erg/Second

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

Formula: erg/s = W × 10,000,000

Reverse: W = erg/s × 1.000000e-7

Step-by-Step Example

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

About Watt

The watt (W) is a unit of power. One watt equals 1 watt. 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.
