Conversion Formula
The formula to convert kilowatts (kW) to horsepower (hp) is: hp = kW × 1.34102. This works because 1 kW is defined as approximately 1.34102 hp, based on the mechanical power equivalence. The multiplication adjusts the power unit from electrical to mechanical measurement.
For example, if you have 4.2 kW: 4.2 × 1.34102 = 5.64 hp. This step-by-step calculation confirms that 4.2 kW equals about 5.64 horsepower, providing a clear link between the two units.
Conversion Example
- Convert 2 kW to hp:
- Multiply 2 by 1.34102
- 2 × 1.34102 = 2.68204
- Result is approximately 2.68 hp
- Convert 10 kW to hp:
- Multiply 10 by 1.34102
- 10 × 1.34102 = 13.4102
- Result is approximately 13.41 hp
- Convert 0.5 kW to hp:
- Multiply 0.5 by 1.34102
- 0.5 × 1.34102 = 0.67051
- Result is about 0.67 hp
- Convert 7.5 kW to hp:
- Multiply 7.5 by 1.34102
- 7.5 × 1.34102 = 10.05765
- Result is roughly 10.06 hp
- Convert 15 kW to hp:
- Multiply 15 by 1.34102
- 15 × 1.34102 = 20.1153
- Result is approximately 20.12 hp
