How to use the Amps to kW Motor calculator
Estimate a three-phase motor's real power in kilowatts from its current, voltage, and power factor using a practical 0.85 preset.
The calculator starts with a 400V three-phase AC preset and a power factor of 0.85. 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.
