Convert 100 Erg/Second (erg/s) to Joule/Second (J/s).

100 Erg/Second equals 1.000000e-5 Joule/Second. Multiply 100 by 1.000000e-7.

100 Erg/Second = 1.000000e-5 Joule/Second

Worked example: converting Erg/Second to Joule/Second

Step 1 — start with the formula. J/s = erg/s × 1.000000e-7
Step 2 — substitute your figure. 100 erg/s × 1.000000e-7
Step 3 — read the result. 100 erg/s = 1.000000e-5 J/s
Step 4 — check it in reverse. erg/s = J/s × 10,000,000 returns 100 erg/s, which matches the figure you started with.

How to Convert Erg/Second to Joule/Second

To convert from Erg/Second (erg/s) to Joule/Second (J/s), multiply the value by 1.000000e-7.

Formula: J/s = erg/s × 1.000000e-7

Reverse: erg/s = J/s × 10,000,000

Step-by-Step Example

Start with your value in Erg/Second. For example: 5 erg/s
Multiply by the conversion factor: 5 x 1.000000e-7
The result is: 5.000000e-7 J/s

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.

About Joule/Second

The joule/second (J/s) is a unit of power. One joule/second 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.
