Quick Intro: Convert kW to Amps
The kW to Amps Calculator helps users convert electrical power in kilowatts into current in amperes based on system voltage and power factor. It supports both single-phase and three-phase AC circuits, making it suitable for residential, commercial, and industrial applications. This tool is especially useful when designing electrical systems, sizing conductors, or verifying equipment ratings. By inputting the kilowatts, voltage, and power factor, users can instantly determine the current drawn by the load. Whether you're an engineer calculating load demands or an electrician checking wiring specs, this tool simplifies the process. It's accurate, reliable, and ideal for quick field reference or detailed planning.
Formula to Convert kW to Amps
- Dc Line: Amps = kW ÷ V
- Single-phase: Amps = (kW × 1000) ÷ (V × PF)
- Three-phase (Line-Line): Amps = (kW × 1000) ÷ (√3 × V × PF)
- Three-phase (Line-Neutral): Amps = (kW × 1000) ÷ (3 × V × PF)
Note: PF = Power Factor (usually 0.8 to 1.0)

Frequently Asked Questions - kW to Amps Calculator:
How do I convert kW to amps?
Use the formula: Amps = (kW × 1000) ÷ (V × PF) for single-phase or divide by (√3 × V × PF) for three-phase.
What is the formula for single-phase?
Amps = (kW × 1000) ÷ (Voltage × Power Factor).
What is the formula for three-phase?
Amps = (kW × 1000) ÷ (√3 × Voltage × Power Factor).
What is the power factor (PF)?
It's the ratio of real power to apparent power, usually between 0.8 and 1.0.
Why do I need voltage for conversion?
Voltage is needed because current depends on both voltage and power.
Is this calculator for AC or DC?
It is for AC systems — single-phase and three-phase.
Can I use this for motors?
Yes, especially when PF is known or assumed.
How accurate is this conversion?
Very accurate if PF and voltage are correct.
What units are used?
Power in kilowatts (kW), voltage in volts (V), current in amps (A).
Is the tool free?
Yes, this calculator is 100% free to use online.
