UK Horsepower Formula:
| From: | To: |
The kilowatt to horsepower conversion is used to convert power measurements between the metric system (kilowatts) and the imperial system (horsepower). The UK horsepower (also known as mechanical horsepower) is commonly used in automotive and engineering applications.
The calculator uses the UK horsepower conversion formula:
Where:
Explanation: This conversion factor represents the exact relationship between kilowatts and UK horsepower, where 1 kilowatt equals approximately 1.34102 horsepower.
Details: Accurate power unit conversion is essential for international engineering projects, automotive specifications, machinery comparisons, and technical documentation that requires standardized power measurements across different unit systems.
Tips: Enter the power value in kilowatts (kW). The value must be positive and greater than zero. The calculator will automatically convert to UK horsepower using the standard conversion factor.
Q1: What is the difference between UK horsepower and other horsepower types?
A: UK horsepower (mechanical horsepower) equals 745.7 watts, while metric horsepower equals 735.5 watts. The US uses the same mechanical horsepower as the UK.
Q2: Why is the conversion factor 1.34102?
A: This factor comes from the definition where 1 horsepower = 745.7 watts, so 1 kW (1000 watts) equals 1000/745.7 ≈ 1.34102 horsepower.
Q3: When is this conversion most commonly used?
A: Primarily in automotive industry for engine power ratings, industrial machinery specifications, and engineering calculations between metric and imperial systems.
Q4: Are there different types of horsepower?
A: Yes, besides mechanical horsepower, there are metric horsepower (PS), boiler horsepower, electrical horsepower, and hydraulic horsepower, each with different conversion factors.
Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between kilowatts and horsepower units.
