This converter allows you to convert electrical horsepower [hp(E)] to mechanical horsepower [hp(I)] or mechanical horsepower [hp(I)] 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)] ≈ 1.0004 mechanical horsepower [hp(I)]1 mechanical horsepower [hp(I)] ≈ 0.9996 electrical horsepower [hp(E)]

Convert electrical horsepower to mechanical horsepower

There are two simple ways to convert electrical horsepower [hp(E)] to mechanical horsepower [hp(I)]. In the first calculation method, the value in electrical horsepower [hp(E)] is divided by the rounded conversion factor of 0.9996. The second method multiplies the value in electrical horsepower [hp(E)] by the rounded conversion factor of 1.0004.

  • Mechanical horsepower [hp(I)] ≈ electrical horsepower [hp(E)] ÷ 0.9996
  • Mechanical horsepower [hp(I)] ≈ electrical horsepower [hp(E)] * 1.0004

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of electrical horsepower [hp(E)] to mechanical horsepower [hp(I)] can be achieved using the following calculation method.

  • Mechanical horsepower [hp(I)] = electrical horsepower [hp(E)] ÷ 27.2155422 ÷ 27.3997801 * 746

Convert mechanical horsepower to electrical horsepower

Converting mechanical horsepower [hp(I)] to electrical horsepower [hp(E)] is easy and can be done in two ways. The first method involves multiplication, in which the value in mechanical horsepower [hp(I)] is multiplied by the rounded conversion factor of 0.9996. The second variant is a division. Here, the value in mechanical horsepower [hp(I)] is divided by the rounded conversion factor of 1.0004.

  • Electrical horsepower [hp(E)] ≈ mechanical horsepower [hp(I)] * 0.9996
  • Electrical horsepower [hp(E)] ≈ mechanical horsepower [hp(I)] ÷ 1.0004

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of mechanical horsepower [hp(I)] to electrical horsepower [hp(E)] can be achieved using the following calculation method.

  • Electrical horsepower [hp(E)] = mechanical horsepower [hp(I)] * 27.2155422 * 27.3997801 ÷ 746

Resistance

Electrical resistance is often expressed in ohms or kiloohms. However, it is also possible to use statohms or deciohms. The resistance converter is ideal for converting between different units of resistance.

Resistance converter

Speed

While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
