1. What is Motor HP to kW Conversion?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: 1 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 motor specifications, electrical systems, and international standards.

4. Using the Calculator

Tips: Simply enter the horsepower value (must be > 0) and the calculator will provide the equivalent in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 0.746?
A: This is the exact conversion factor defined by the international standard, where 1 HP = 745.69987158227022 watts (rounded to 0.746 kW).

Q2: Is this conversion the same for all types of HP?
A: This calculator uses mechanical horsepower. Other types (metric, boiler, electrical) have slightly different conversion factors.

Q3: When would I need to convert HP to kW?
A: When working with electrical systems (rated in kW) that power mechanical equipment (rated in HP), or when comparing international specifications.

Q4: How precise is this conversion?
A: The conversion is precise to 3 decimal places (0.746) which is sufficient for most practical applications.

Q5: Can I convert kW back to HP?
A: Yes, simply divide the kW value by 0.746 to get HP.
