Kilowatts to Horsepower Formula:
From: | To: |
Kilowatts (kW) and horsepower (HP) are both units of power measurement. Kilowatts are part of the metric system (SI units), while horsepower is an imperial unit commonly used in automotive and mechanical engineering applications.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts power measurements from the metric system (kilowatts) to the imperial system (horsepower) using the standard conversion factor.
Details: Accurate power conversion is essential for comparing engine performance, electrical motor specifications, and mechanical power ratings across different measurement systems used in various countries and industries.
Tips: Enter the kilowatt value you wish to convert. The value must be positive and valid. The calculator will automatically compute the equivalent horsepower value.
Q1: What is the exact conversion factor?
A: 1 horsepower = 0.745699872 kilowatts. We use 0.7457 for practical calculations, which provides sufficient accuracy for most applications.
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, which is the most common standard.
Q3: When is this conversion most commonly used?
A: This conversion is frequently used in automotive industries, engine specifications, electric motor ratings, and when comparing power outputs between metric and imperial systems.
Q4: How accurate is this conversion?
A: The conversion is mathematically precise based on the defined relationship between the two units. For engineering applications requiring extreme precision, more decimal places may be used.
Q5: Can I convert horsepower back to kilowatts?
A: Yes, to convert horsepower to kilowatts, multiply the horsepower value by 0.7457 (kW = HP × 0.7457).
