Converting 7.5 kW to HP: Result and Explanation
The conversion of 7.5 kilowatts to horsepower results in approximately 10.065 HP.
To convert kilowatts to horsepower, the common formula multiplies the kilowatt value by 1.34102. Since 1 kW equals exactly 1.34102 HP, multiplying 7.5 kW by this factor gives the equivalent horsepower, which helps in understanding motor power across different measurement systems.
Understanding the Conversion
Converting 7.5 kW to HP involves using the fixed ratio where 1 kilowatt equals 1.34102 horsepower. This ratio is based on the definition of mechanical horsepower, which originated from the work a horse could do. By multiplying 7.5 by 1.34102, you get the horsepower equivalent, approximately 10.065 HP.

Conversion Formula
The formula to convert kilowatts to horsepower is: HP = kW × 1.34102. This works because 1 kW equals 1.34102 HP, which is a fixed conversion ratio based on the definition of mechanical horsepower. For example, converting 7.5 kW: 7.5 × 1.34102 = 10.06515 HP, showing the direct proportionality between the units.
Conversion Example
- Convert 10 kW to HP:
- Multiply 10 by 1.34102
- 10 × 1.34102 = 13.4102 HP
- Result: 10 kW equals approximately 13.4102 HP
- Convert 5 kW to HP:
- Multiply 5 by 1.34102
- 5 × 1.34102 = 6.7051 HP
- Result: 5 kW equals approximately 6.7051 HP
- Convert 12.5 kW to HP:
- Multiply 12.5 by 1.34102
- 12.5 × 1.34102 = 16.76275 HP
- Result: 12.5 kW equals approximately 16.7628 HP
