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 specifications 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 equals exactly 0.745699872 kilowatts. The calculator uses 0.746 for simplicity.

3. Importance of Power Unit Conversion

Details: Converting between HP and kW is essential when working with international equipment specifications or electrical systems.

4. Using the Calculator

Tips: Simply enter the motor power in horsepower. The result will show the equivalent power in kilowatts.

5. Frequently Asked Questions (FAQ)
