1. What is the kW to HP Conversion?

The kW to HP conversion calculates horsepower from kilowatts for three-phase electrical systems. This conversion is essential for comparing power ratings between different measurement systems used in industrial and mechanical applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( HP \) — Horsepower
• \( kW \) — Kilowatts
• \( 0.7457 \) — Conversion factor (1 HP = 0.7457 kW)

Explanation: The formula converts power measurements from kilowatts to horsepower using the standard conversion factor for three-phase systems.

3. Importance of Power Conversion

Details: Accurate power conversion is crucial for equipment specification, motor selection, and compatibility assessment between different power measurement systems used in industrial applications.

4. Using the Calculator

Tips: Enter kilowatt value in the input field. The value must be a positive number greater than zero for accurate conversion.
