How to use the Amps to kW 3 Phase calculator
Convert three-phase amps to kilowatts using line voltage, current, power factor, and the square-root-of-three multiplier.
The calculator starts with a 400V three-phase AC preset and a power factor of 1. Enter either current or power, adjust the electrical settings to match the equipment nameplate, and the result updates immediately.
Formula used
For this three-phase AC conversion, the calculator uses (Amps × Volts × √3 × PF) ÷ 1000. Use the actual supply voltage and the equipment's rated power factor whenever accuracy matters.
