How to use the EV Charger Amps to kW calculator
Convert EV charger amps to kilowatts for a 240V single-phase circuit to estimate charging power and compare charger ratings.
The calculator starts with a 240V single-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 single-phase AC conversion, the calculator uses (Amps × Volts × PF) ÷ 1000. Use the actual supply voltage and the equipment's rated power factor whenever accuracy matters.
