How to Convert Erg/Second to BTU/Hour

To convert from Erg/Second (erg/s) to BTU/Hour (BTU/h), multiply the value by 3.412142e-7.

Formula: BTU/h = erg/s × 3.412142e-7

Reverse: erg/s = BTU/h × 2,930,710.7017222

Step-by-Step Example

Start with your value in Erg/Second. For example: 5 erg/s
Multiply by the conversion factor: 5 x 3.412142e-7
The result is: 1.706071e-6 BTU/h

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/Hour

The btu/hour (BTU/h) is a unit of power. One btu/hour equals 0.2930710702 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.
