This converter allows you to convert electrical horsepower [hp(E)] to gigawatts [GW] or gigawatts [GW] 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.
Convert electrical horsepower to gigawatts
There are two simple ways to convert electrical horsepower [hp(E)] to gigawatts [GW]. In the first calculation method, the value in electrical horsepower [hp(E)] is divided by the rounded conversion factor of 1,340,482.5737. The second method multiplies the value in electrical horsepower [hp(E)] by 7.46 * 10-7.
- Gigawatts [GW] ≈ electrical horsepower [hp(E)] ÷ 1,340,482.5737
- Gigawatts [GW] = electrical horsepower [hp(E)] * 7.46 * 10-7
However, the calculation method with rounded conversion values is only suitable for rough conversions from electrical horsepower [hp(E)] to gigawatts [GW], as rounding errors may occur in the calculation results. The following formula shows another variant that can be used to calculate results as accurately as possible.
- Gigawatts [GW] = electrical horsepower [hp(E)] * 746 ÷ 109
Convert gigawatts to electrical horsepower
Converting gigawatts [GW] to electrical horsepower [hp(E)] is easy and can be done in two ways. The first method involves multiplication, in which the value in gigawatts [GW] is multiplied by the rounded conversion factor of 1,340,482.5737. The second variant is a division. Here, the value in gigawatts [GW] is divided by 7.46 * 10-7.
- Electrical horsepower [hp(E)] ≈ gigawatts [GW] * 1,340,482.5737
- Electrical horsepower [hp(E)] = gigawatts [GW] ÷ (7.46 * 10-7)
However, the version with rounded conversion values can produce somewhat inaccurate calculation results, which is why it is only suitable for rough conversions from gigawatts [GW] to electrical horsepower [hp(E)]. The formula below shows an alternative method that can be used to calculate results as accurately as possible.
- Electrical horsepower [hp(E)] = gigawatts [GW] ÷ 746 * 109

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.
