Power Conversion Formula:
| From: | To: |
The horsepower to watts conversion is a standard unit conversion that transforms mechanical power (horsepower) to electrical power (watts). This conversion is independent of phase and applies universally.
The calculator uses the conversion formula:
Where:
Explanation: This conversion factor (746 watts per horsepower) is based on the mechanical equivalent of heat and represents the standard conversion between these two power units.
Details: Accurate power conversion is essential for electrical engineering applications, motor sizing, energy efficiency calculations, and comparing power ratings across different measurement systems.
Tips: Enter horsepower value (must be greater than 0). The calculator will automatically convert to watts using the standard conversion factor of 746 watts per horsepower.
Q1: Why is the conversion factor 746?
A: The conversion factor of 746 watts per horsepower is derived from the mechanical equivalent of heat and represents the standard conversion between these power units.
Q2: Does this conversion apply to both single and three-phase systems?
A: Yes, this is a unit conversion that is independent of phase. The conversion from horsepower to watts remains the same regardless of the electrical system phase.
Q3: What are typical horsepower ratings for motors?
A: Motor horsepower ratings vary widely, from fractional horsepower (less than 1 HP) for small applications to hundreds or thousands of HP for industrial applications.
Q4: When would I need to convert horsepower to watts?
A: This conversion is commonly needed for electrical system design, energy consumption calculations, motor selection, and comparing power ratings across different measurement standards.
Q5: Are there different types of horsepower?
A: Yes, there are several definitions (mechanical, metric, electrical), but this calculator uses the standard mechanical horsepower (1 HP = 746 watts) which is most commonly used.
