1. What is Horsepower to kW Conversion?

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

Purpose: It helps engineers, mechanics, and technicians work with power measurements in different unit systems.

2. How Does the Conversion Work?

The conversion uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts
• \( HP \) — Power in horsepower

Explanation: 1 mechanical horsepower is equivalent to approximately 0.746 kilowatts.

3. Importance of Power Unit Conversion

Details: Converting between HP and kW is essential when working with international specifications, electrical systems, or comparing engine performance.

4. Using the Calculator

Tips: Simply enter the horsepower value and the calculator will instantly provide the equivalent in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Is this conversion for mechanical or electrical horsepower?
A: This uses mechanical horsepower (1 HP = 0.746 kW). Metric horsepower is slightly different (1 HP = 0.7355 kW).

Q2: Why is the conversion factor 0.746?
A: This comes from the original definition of horsepower (550 ft-lb/s) converted to watts (745.7 W).

Q3: How accurate is this conversion?
A: The conversion is precise to three decimal places for most practical applications.

Q4: Can I convert kW back to HP?
A: Yes, divide kW by 0.746 to get HP (or use our kW to HP calculator).

Q5: Does this work for all types of horsepower?
A: No, this is specifically for mechanical horsepower. Other types (metric, boiler, electric) have different conversion factors.
