Power Conversion Formula:
From: | To: |
Definition: This calculator converts power measurements from horsepower (HP) to kilowatts (kW).
Purpose: It helps engineers, mechanics, and technicians convert between these common power units used in different measurement systems.
The converter uses the formula:
Where:
Explanation: 1 mechanical horsepower is equal to approximately 0.746 kilowatts.
Details: Proper conversion ensures accurate specifications when working with equipment rated in different units and comparing performance metrics.
Tips: Simply enter the horsepower value and the calculator will automatically compute the equivalent kilowatts.
Q1: Why is the conversion factor 0.746?
A: This comes from the definition of 1 HP = 550 ft-lb/s = 745.7 watts (rounded to 0.746 kW).
Q2: Does this work for all types of horsepower?
A: This conversion is for mechanical horsepower. Metric horsepower uses 0.7355 kW/HP.
Q3: When would I need this conversion?
A: When comparing engine specifications, sizing electrical systems, or working with international standards.
Q4: How precise is this conversion?
A: The 0.746 factor provides precision to three decimal places, sufficient for most applications.
Q5: Can I convert kW back to HP?
A: Yes, divide kW by 0.746 or multiply by 1.341 to get HP.
