Conversion Formula:
| From: | To: |
The horsepower to kilowatts conversion is a standard calculation used to convert power measurements between the imperial system (horsepower) and the metric system (kilowatts). This conversion is commonly used in automotive, engineering, and electrical applications.
The calculator uses the conversion formula:
Where:
Explanation: One mechanical horsepower is equivalent to approximately 0.7457 kilowatts. This conversion factor is standardized for most practical applications.
Details: Accurate power unit conversion is essential for international engineering projects, automotive specifications comparison, electrical system design, and equipment compatibility across different measurement systems.
Tips: Enter the horsepower value in the input field. The value must be a positive number. The calculator will automatically compute and display the equivalent power in kilowatts.
Q1: Is the conversion factor the same for all types of horsepower?
A: The 0.7457 conversion factor applies to mechanical horsepower. Metric horsepower uses a slightly different factor (0.7355), and other types may vary.
Q2: Why convert horsepower to kilowatts?
A: Kilowatts are the standard SI unit for power and are used worldwide, while horsepower is primarily used in the US and UK. Conversion allows for international comparison.
Q3: How accurate is this conversion?
A: The conversion is accurate for most practical purposes. The factor 0.7457 is standardized and widely accepted in engineering applications.
Q4: Can I convert kilowatts back to horsepower?
A: Yes, to convert kilowatts to horsepower, divide the kilowatt value by 0.7457 (or multiply by approximately 1.341).
Q5: Where is this conversion most commonly used?
A: This conversion is frequently used in automotive industries (engine power ratings), electrical engineering (motor specifications), and equipment manufacturing.
