Kilowatts to amps formula

Amps = 1000 × kW ÷ (V × PF)

Single-phase AC: A = 1000 × kW ÷ (V × PF); DC: A = 1000 × kW ÷ V.
Three-phase AC: A = 1000 × kW ÷ (√3 × V × PF).

Example: 1000 × 5 kW ÷ 240 V = 20.8333 A.

Reverse formula: kW = A × V × PF ÷ 1000. Example: 32 A × 230 V ÷ 1000 = 7.36 kW.

For continuous loads such as EV chargers, size the breaker so the load is no more than 80% of its rating.

About kilowatts and amps

Kilowatts (kW). The kilowatt is 1,000 watts, used to rate heaters, motors, chargers and generators.

Amps (A). The ampere (amp) is the SI unit of electric current: the flow of electric charge through a circuit.

Frequently asked questions

How do you convert kW to amps?

Amps = 1000 × kW ÷ (V × PF) for single-phase AC, 1000 × kW ÷ V for DC, and 1000 × kW ÷ (1.732 × V × PF) for three-phase.

How many amps is 7.4 kW?

At 230 V single-phase, 7.4 kW is about 32 A, the common rating of a home EV charger. At 240 V it is 30.8 A.

How many amps is 10 kW three-phase at 400 V?

10 kW ÷ (1.732 × 400 V) = 14.4 A per phase at a power factor of 1.

Why do I need the power factor?

AC motors and electronics draw extra current that does no useful work. A lower power factor means more amps for the same kW.

What is 10 kilowatts in amps?

10 kW is 41.6667 A. This assumes 240 V single-phase and a power factor of 1.

Is this converter free and private?

Yes. It is free with no sign-up, and every calculation runs in your browser, so nothing you type is sent to a server.
