How to Convert Kilojoule/Hour to Erg/Second

To convert from Kilojoule/Hour (kJ/h) to Erg/Second (erg/s), multiply the value by 2,777,777.777777778.

Formula: erg/s = kJ/h × 2,777,777.777777778

Reverse: kJ/h = erg/s × 3.600000e-7

Step-by-Step Example

Start with your value in Kilojoule/Hour. For example: 5 kJ/h
Multiply by the conversion factor: 5 x 2,777,777.777777778
The result is: 13,888,888.888889 erg/s

About Kilojoule/Hour

The kilojoule/hour (kJ/h) is a unit of power. One kilojoule/hour equals 0.2777777778 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.
