This converter allows you to convert electrical horsepower [hp(E)] to terawatts [TW] or terawatts [TW] 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)] = 7.46 * 10-10 terawatts [TW]1 terawatt [TW] ≈ 1.34 * 109 electrical horsepower [hp(E)]

Convert electrical horsepower to terawatts

There are two simple ways to convert electrical horsepower [hp(E)] to terawatts [TW]. In the first calculation method, the value in electrical horsepower [hp(E)] is divided by the rounded conversion factor of 1.34 * 109. The second method multiplies the value in electrical horsepower [hp(E)] by 7.46 * 10-10.

  • Terawatts [TW] ≈ electrical horsepower [hp(E)] ÷ (1.34 * 109)
  • Terawatts [TW] = electrical horsepower [hp(E)] * 7.46 * 10-10

However, the calculation method with rounded conversion values is only suitable for rough conversions from electrical horsepower [hp(E)] to terawatts [TW], 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.

  • Terawatts [TW] = electrical horsepower [hp(E)] * 746 ÷ 1012

Convert terawatts to electrical horsepower

Converting terawatts [TW] to electrical horsepower [hp(E)] is easy and can be done in two ways. The first method involves multiplication, in which the value in terawatts [TW] is multiplied by the rounded conversion factor of 1.34 * 109. The second variant is a division. Here, the value in terawatts [TW] is divided by 7.46 * 10-10.

  • Electrical horsepower [hp(E)] ≈ terawatts [TW] * 1.34 * 109
  • Electrical horsepower [hp(E)] = terawatts [TW] ÷ (7.46 * 10-10)

However, the version with rounded conversion values can produce somewhat inaccurate calculation results, which is why it is only suitable for rough conversions from terawatts [TW] 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)] = terawatts [TW] ÷ 746 * 1012

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.
