1. What is a kW to HP Converter?

Definition: This calculator converts electric motor power from kilowatts (kW) to horsepower (HP).

Purpose: It helps engineers, technicians, and motor specifiers easily convert between these common power units.

2. How Does the Converter Work?

The converter uses the formula:

Where:

• \( HP \) — Horsepower (mechanical power)
• \( P_{kW} \) — Power in kilowatts

Explanation: 1 kilowatt is approximately equal to 1.341 horsepower. This conversion factor is based on the mechanical equivalent of power.

3. Importance of Power Unit Conversion

Details: Different industries use different power units - electrical systems typically use kW while mechanical systems often use HP. Proper conversion ensures accurate specifications and comparisons.

4. Using the Converter

Tips: Simply enter the motor power in kilowatts (must be > 0) and the converter will display the equivalent horsepower.

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion exact?
A: The conversion factor 1.34102 is rounded to 1.341 for practical use. For precise calculations, use 1.34102.

Q2: Does this work for all types of horsepower?
A: This converts to mechanical horsepower (HP). For metric horsepower (PS), use 1.35962 instead.

Q3: Why convert kW to HP?
A: Many motor specifications in North America use HP, while electrical ratings use kW. Conversion allows comparison.

Q4: What's a typical kW to HP ratio?
A: A 1 kW motor ≈ 1.34 HP, 10 kW ≈ 13.41 HP, 100 kW ≈ 134.1 HP.

Q5: Can I convert HP back to kW?
A: Yes, divide HP by 1.341 or multiply by 0.7457 (the inverse factor).
