How to Convert Erg/Second to BTU/Second

To convert from Erg/Second (erg/s) to BTU/Second (BTU/s), multiply the value by 9.478171e-11.

Formula: BTU/s = erg/s × 9.478171e-11

Reverse: erg/s = BTU/s × 1.055056e+10

Step-by-Step Example

Start with your value in Erg/Second. For example: 5 erg/s
Multiply by the conversion factor: 5 x 9.478171e-11
The result is: 4.739086e-10 BTU/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 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.
