This converter allows you to convert electrical horsepower [hp(E)] to kilojoules per second [kJ/s] or kilojoules per second [kJ/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)] = 0.746 kilojoules per second [kJ/s]1 kilojoule per second [kJ/s] ≈ 1.3405 electrical horsepower [hp(E)]

Convert electrical horsepower to kilojoules per second

There are two simple ways to convert electrical horsepower [hp(E)] to kilojoules per second [kJ/s]. In the first calculation method, the value in electrical horsepower [hp(E)] is divided by the rounded conversion factor of 1.3405. The second method multiplies the value in electrical horsepower [hp(E)] by 0.746.

  • Kilojoules per second [kJ/s] ≈ electrical horsepower [hp(E)] ÷ 1.3405
  • Kilojoules per second [kJ/s] = electrical horsepower [hp(E)] * 0.746

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


Convert kilojoules per second to electrical horsepower

Converting kilojoules per second [kJ/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 kilojoules per second [kJ/s] is multiplied by the rounded conversion factor of 1.3405. The second variant is a division. Here, the value in kilojoules per second [kJ/s] is divided by 0.746.

  • Electrical horsepower [hp(E)] ≈ kilojoules per second [kJ/s] * 1.3405
  • Electrical horsepower [hp(E)] = kilojoules per second [kJ/s] ÷ 0.746

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