This converter allows you to convert kilowatts [kW] to mechanical horsepower [hp(I)] or mechanical horsepower [hp(I)] to kilowatts [kW]. 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 kilowatt [kW] ≈ 1.341 mechanical horsepower [hp(I)]1 mechanical horsepower [hp(I)] ≈ 0.7457 kilowatts [kW]

Convert kilowatts to mechanical horsepower

There are two simple ways to convert kilowatts [kW] to mechanical horsepower [hp(I)]. In the first calculation method, the value in kilowatts [kW] is divided by the rounded conversion factor of 0.7457. The second method multiplies the value in kilowatts [kW] by the rounded conversion factor of 1.341.

  • Mechanical horsepower [hp(I)] ≈ kilowatts [kW] ÷ 0.7457
  • Mechanical horsepower [hp(I)] ≈ kilowatts [kW] * 1.341

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

  • Mechanical horsepower [hp(I)] = kilowatts [kW] ÷ 0.272155422 ÷ 2.73997801

Convert mechanical horsepower to kilowatts

Converting mechanical horsepower [hp(I)] to kilowatts [kW] 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 0.7457. The second variant is a division. Here, the value in mechanical horsepower [hp(I)] is divided by the rounded conversion factor of 1.341.

  • Kilowatts [kW] ≈ mechanical horsepower [hp(I)] * 0.7457
  • Kilowatts [kW] ≈ mechanical horsepower [hp(I)] ÷ 1.341

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 kilowatts [kW] can be achieved using the following calculation method.

  • Kilowatts [kW] = mechanical horsepower [hp(I)] * 0.272155422 * 2.73997801

Pressure

Hectopascals, millibars, and bars are just a few examples of the many units of pressure. The pressure converter makes conversion a breeze and ensures that the results are accurate and precise.

Pressure converter

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.
