How to Convert Joule/Second to Horsepower (Elec)

To convert from Joule/Second (J/s) to Horsepower (Elec) (hp (E)), multiply the value by 0.0013404826.

Formula: hp (E) = J/s × 0.0013404826

Reverse: J/s = hp (E) × 746

Step-by-Step Example

Start with your value in Joule/Second. For example: 5 J/s
Multiply by the conversion factor: 5 x 0.0013404826
The result is: 0.006702 hp (E)

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.

About Horsepower (Elec)

The horsepower (elec) (hp (E)) is a unit of power. One horsepower (elec) equals 746 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.
