The conversion of 800 horsepower (hp) to kilowatts (kw) gives approximately 588.6 kw.
Since 1 horsepower equals about 0.7355 kilowatts, multiplying 800 hp by this factor results in the kilowatt value. This means that if you have a machine rated at 800 hp, it produces roughly 588.6 kw of power, based on the conversion factor.
Understanding the conversion: hp to kw
The conversion formula from horsepower to kilowatts is straightforward: multiply the horsepower value by 0.7355. This works because horsepower and kilowatts are both units measuring power but in different systems. The number 0.7355 is derived from the exact relationship between the two units, where 1 hp equals 745.7 watts, and 1 kilowatt equals 1000 watts. So, dividing 745.7 by 1000 gives 0.7457, but for mechanical horsepower, the more precise factor is 0.7355. For example, converting 800 hp: 800 × 0.7355 = 588.4 kw (rounded). This formula is used in engineering and physics to switch between the two power units efficiently.

Conversion Formula
The formula for converting hp into kw involves multiplying the horsepower value by 0.7355. This works because horsepower and kilowatts are units that measure power, but they belong to different measurement systems. The 0.7355 factor comes from the exact ratio where 1 hp equals 745.7 watts, and since 1 kw equals 1000 watts, dividing 745.7 by 1000 results in 0.7457, but for mechanical horsepower, 0.7355 is used. For example, to convert 100 hp: 100 × 0.7355 = 73.55 kw. This makes it easy to switch from one unit to the other by simple multiplication.
Conversion Example
- Convert 500 hp to kw:
- Multiply 500 by 0.7355
- 500 × 0.7355 = 367.75 kw
- Convert 1000 hp to kw:
- Multiply 1000 by 0.7355
- 1000 × 0.7355 = 735.50 kw
- Convert 250 hp to kw:
- Multiply 250 by 0.7355
- 250 × 0.7355 = 183.875 kw
- Convert 120 hp to kw:
- Multiply 120 by 0.7355
- 120 × 0.7355 = 88.26 kw
- Convert 750 hp to kw:
- Multiply 750 by 0.7355
- 750 × 0.7355 = 551.625 kw

Conversion Definitions
hp
Horsepower (hp) is a unit measuring the power output of engines and motors, originally developed to compare the power of steam engines to horses. It equals about 745.7 watts, used in automotive, machinery, and mechanical contexts to describe engine strength.
kw
Kilowatt (kw) is a metric power unit equal to 1000 watts, used globally for electrical power and mechanical power measurement. It simplifies large power values, making it easier to compare and calculate energy output in various fields like engineering and energy sectors.
Conversion FAQs
Can I convert 800 hp into kw directly with a calculator?
Yes, by multiplying 800 by 0.7355, you can find the kw equivalent. Many calculators or the provided tool can do this instantly, providing a quick answer without manual calculations. Just enter 800 in the tool, and it will display the kw value.
Is the conversion factor the same for all types of horsepower?
No, different types of horsepower exist, like mechanical, electrical, and metric horsepower, each with slightly different conversion factors. The factor 0.7355 is for mechanical horsepower; others may vary, so ensure you’re using the right one for your context.
Why is there a difference between 588.6 and 588.4 kw in the calculations?
The slight difference arises due to rounding and the exact value used for the conversion factor. The precise conversion is 1 hp = 745.7 watts, which gives 588.6 kw for 800 hp when rounding to four decimals. Small variations are normal depending on precision.
Can I use this conversion for electric vehicle motors?
Yes, but ensure that the horsepower rating is of the mechanical power output. For electric motors, the conversion to kw is relevant, but you should check if the horsepower value is based on mechanical or electrical measurements, as they can differ slightly.
