This kW to amps calculator helps you convert kilowatts (kW) into amperes (A) quickly and accurately.

It supports both single-phase and three-phase electrical systems, with voltage and power factor inputs to get the correct result for your setup.

Formula:

The formula depends on the type of current:

Single-phase AC:

Amps (A) = (kW × 1000) / (Voltage × Power Factor)

Three-phase AC:

Amps (A) = (kW × 1000) / (√3 × Voltage × Power Factor)

Where:

• kW = Power in kilowatts
• Voltage (V) = Line voltage
• Power Factor (PF) = Efficiency factor (typically between 0.8 and 1)
• √3 ≈ 1.732 (for three-phase systems)

Example:

Let’s convert 10 kW to amps in a single-phase system at 230V with a power factor of 0.9:

Amps = (10 × 1000) / (230 × 0.9) = 48.31 A

Now for a three-phase system with the same values:

Amps = (10 × 1000) / (1.732 × 230 × 0.9) ≈ 27.9 A

How to Use the Calculator?

1. Choose the system: Single-phase or Three-phase
2. Enter the power in kW
3. Input the voltage (V)
4. Enter the power factor (default is 0.9)
