Wattage to Amperage
I = P/V or I = P/(√3 V PF)
How to Use This Calculator
Choose phase, enter power (W) and voltage (V). For three-phase, include power factor to convert watts to amps.
Formula
I_single = P / V
I_three = P / (√3 V PF)
Frequently Asked Questions
kW vs W?
If you have kW, convert: W = kW × 1000 before using the calculator.
