This converter allows you to convert electrical horsepower [hp(E)] to joules per second [J/s] or joules per second [J/s] to electrical horsepower [hp(E)]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 electrical horsepower [hp(E)] = 746 joules per second [J/s]1 joule per second [J/s] ≈ 0.0013 electrical horsepower [hp(E)]

Convert electrical horsepower to joules per second

There are two simple ways to convert electrical horsepower [hp(E)] to joules per second [J/s]. In the first calculation method, the value in electrical horsepower [hp(E)] is divided by the rounded conversion factor of 0.0013. The second method multiplies the value in electrical horsepower [hp(E)] by 746.

  • Joules per second [J/s] ≈ electrical horsepower [hp(E)] ÷ 0.0013
  • Joules per second [J/s] = electrical horsepower [hp(E)] * 746

The calculation method with a rounded conversion value is more suitable for rough conversions from electrical horsepower [hp(E)] to joules per second [J/s], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert joules per second to electrical horsepower

Converting joules per second [J/s] to electrical horsepower [hp(E)] is easy and can be done in two ways. The first method involves multiplication, in which the value in joules per second [J/s] is multiplied by the rounded conversion factor of 0.0013. The second variant is a division. Here, the value in joules per second [J/s] is divided by 746.

  • Electrical horsepower [hp(E)] ≈ joules per second [J/s] * 0.0013
  • Electrical horsepower [hp(E)] = joules per second [J/s] ÷ 746

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from joules per second [J/s] to electrical horsepower [hp(E)] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
