Conversion Formula
The formula to convert horsepower to kilowatts is: kw = hp × 0.7355. This works because 1 horsepower is officially defined as exactly 745.7 watts, and since 1 kilowatt equals 1000 watts, dividing 745.7 by 1000 gives 0.7457. However, the more common conversion uses 0.7355 for simplicity.
For example, with 250 hp: 250 × 0.7355 = 183.875 kw. This step-by-step multiplication ensures accurate conversion based on the standard factor, making it easy to switch between units for calculations or engineering purposes.
Conversion Example
- Convert 100 hp to kw:
- Multiply 100 by 0.7355
- Result: 100 × 0.7355 = 73.55 kw
- Convert 300 hp to kw:
- Multiply 300 by 0.7355
- Result: 300 × 0.7355 = 220.65 kw
- Convert 50 hp to kw:
- Multiply 50 by 0.7355
- Result: 50 × 0.7355 = 36.775 kw
- Convert 400 hp to kw:
- Multiply 400 by 0.7355
- Result: 400 × 0.7355 = 294.2 kw
- Convert 75 hp to kw:
- Multiply 75 by 0.7355
- Result: 75 × 0.7355 = 55.1625 kw

Conversion Definitions
hp
Horsepower (hp) is a unit measuring power, originally based on the power output of horses, now standardized as 745.7 watts for mechanical horsepower, used mainly in automotive and engine performance contexts to indicate an engine’s strength.
kw
Kilowatt (kw) is a metric power unit equal to 1000 watts, used globally in electrical, mechanical, and power generation industries to express energy transfer rates, motor capacities, and electrical power consumption.
Conversion FAQs
What is the precise formula to convert 250 hp into kw?
The exact formula is: kw = hp × 0.7355. Therefore, for 250 hp, multiply 250 by 0.7355, resulting in 183.875 kw. This calculation is based on the standard conversion factor, ensuring accurate unit translation.
Why do different sources sometimes give slightly different conversion factors in hp to kw?
Different standards or definitions of horsepower (mechanical, electrical, metric) lead to minor variations in the conversion factors. The most common is 0.7355, but some sources use 0.746, resulting in slightly higher kw values.
Is the conversion from hp to kw reversible? How?
Yes, reversing the conversion involves dividing the kw value by 0.7355 to get hp. For example, to find hp from 186 kw, divide 186 by 0.7355, which gives approximately 253 hp, confirming the relation between the units.
