Conversion Formula:
| From: | To: |
Kilowatts (kW) and horsepower (HP) are both units of power measurement. The conversion between these units is essential in various fields including automotive engineering, industrial machinery, and electrical systems where different regions use different standard units.
The calculator uses the standard conversion formula:
Where:
Explanation: This conversion factor represents the exact relationship between mechanical horsepower and kilowatts in the imperial measurement system.
Details: Accurate power unit conversion is crucial for international engineering projects, vehicle specifications comparison, machinery import/export, and technical documentation that needs to be understood across different measurement systems.
Tips: Enter the kilowatt value you wish to convert. The value must be zero or positive. The calculator will instantly provide the equivalent horsepower value with two decimal precision.
Q1: What is the exact conversion factor?
A: The exact conversion factor is 1 kilowatt = 1.34102209 horsepower, though 1.341 is commonly used for practical calculations.
Q2: Are there different types of horsepower?
A: Yes, there are mechanical horsepower (hp(I)), metric horsepower (PS), and electrical horsepower. This calculator uses mechanical horsepower.
Q3: Which countries use horsepower vs kilowatts?
A: Horsepower is commonly used in the United States and United Kingdom, while kilowatts are the standard in most other countries and in scientific contexts.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact for mechanical horsepower, providing reliable results for engineering and technical applications.
Q5: Can I convert horsepower back to kilowatts?
A: Yes, to convert horsepower to kilowatts, divide the horsepower value by 1.341 or multiply by 0.7457.
