This converter allows you to convert watts [W] to electrical horsepower [hp(E)] or electrical horsepower [hp(E)] to watts [W]. 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 watt [W] ≈ 0.0013 electrical horsepower [hp(E)]1 electrical horsepower [hp(E)] = 746 watts [W]

Convert watts to electrical horsepower

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

  • Electrical horsepower [hp(E)] = watts [W] ÷ 746
  • Electrical horsepower [hp(E)] ≈ watts [W] * 0.0013

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


Convert electrical horsepower to watts

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

  • Watts [W] = electrical horsepower [hp(E)] * 746
  • Watts [W] ≈ electrical horsepower [hp(E)] ÷ 0.0013

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