How to Convert BTU/Second to Erg/Second

To convert from BTU/Second (BTU/s) to Erg/Second (erg/s), multiply the value by 10,550,558,526.2.

Formula: erg/s = BTU/s × 1.055056e+10

Reverse: BTU/s = erg/s × 9.478171e-11

Step-by-Step Example

Start with your value in BTU/Second. For example: 5 BTU/s
Multiply by the conversion factor: 5 x 10,550,558,526.2
The result is: 52,752,792,631 erg/s

About BTU/Second

The btu/second (BTU/s) is a unit of power. One btu/second equals 1055.055853 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.
