1. What is HP to kW Conversion?

The HP to kW conversion is used to translate mechanical power (horsepower) to electrical power (kilowatts). This conversion is essential in various engineering and industrial applications where different power units are used.

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Where:

• \( HP \) — Horsepower (mechanical power unit)
• \( kW \) — Kilowatt (electrical power unit)
• \( 0.7457 \) — Conversion factor (exact value)

Explanation: One mechanical horsepower is equivalent to approximately 745.7 watts, or 0.7457 kilowatts.

3. Importance of Power Unit Conversion

Details: Accurate power unit conversion is crucial for equipment specification, energy calculations, and compatibility between mechanical and electrical systems.

4. Using the Calculator

Tips: Enter horsepower value (must be positive number) and click calculate to get the equivalent kilowatt value.

5. Frequently Asked Questions (FAQ)

Q1: Is the conversion factor exact?
A: Yes, 1 HP = 0.745699872 kW exactly by definition.

Q2: What's the difference between mechanical and electrical HP?
A: This calculator uses mechanical HP (550 ft·lbf/s). Electrical HP is slightly different (746 W).

Q3: How precise is this conversion?
A: The conversion is mathematically exact, though practical measurements may have precision limits.

Q4: When is this conversion needed?
A: Common in automotive, industrial machinery, and power generation applications.

Q5: Can I convert kW back to HP?
A: Yes, by dividing kW by 0.7457 (or multiplying by ~1.341).
