Conversion Formula:
| From: | To: |
The horsepower to kilowatts conversion is a fundamental unit conversion used to translate mechanical power (horsepower) to electrical power (kilowatts). This conversion is essential in various engineering, automotive, and industrial applications where power measurements need to be standardized.
The calculator uses the standard conversion formula:
Where:
Explanation: The conversion factor 0.7457 represents the exact mathematical relationship between one horsepower and one kilowatt, where 1 HP equals approximately 0.7457 kilowatts.
Details: Accurate power unit conversion is crucial for engineering calculations, equipment specifications, international standards compliance, and comparing power outputs across different measurement systems used worldwide.
Tips: Enter horsepower value in the input field. The value must be positive and greater than zero. The calculator will automatically compute and display the equivalent kilowatt value with four decimal places precision.
Q1: Why is the conversion factor 0.7457?
A: The factor 0.7457 comes from the exact definition where 1 horsepower equals 745.7 watts, and since 1 kilowatt equals 1000 watts, the conversion becomes 0.7457 kW per HP.
Q2: Are there different types of horsepower?
A: Yes, there are mechanical horsepower (hp(I)), metric horsepower (PS), and electrical horsepower. This calculator uses the standard mechanical horsepower (1 hp = 745.7 W).
Q3: Where is this conversion commonly used?
A: This conversion is widely used in automotive industry, electrical engineering, mechanical engineering, and when comparing engine power specifications internationally.
Q4: How accurate is this conversion?
A: The conversion is mathematically exact for standard mechanical horsepower. The calculator provides results with four decimal places for precision.
Q5: Can I convert kilowatts back to horsepower?
A: Yes, to convert kilowatts to horsepower, use the formula: HP = kW ÷ 0.7457 or HP = kW × 1.34102.
