How to Convert Kilowatt to Erg/Second

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

Formula: erg/s = kW × 1.000000e+10

Reverse: kW = erg/s × 1.000000e-10

Step-by-Step Example

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

About Kilowatt

The kilowatt (kW) is a unit of power. One kilowatt equals 1000 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.
