Calculator 07 / Power conversion

Amps ↔ kW

Convert between current and real power for single- and three-phase loads — kW = V·I·PF·√3/1000 (three-phase) or V·I·PF/1000 (single-phase) — with the formula shown.

Converted value

10 A = 2.3 kW

kW = 230 × 10 × 1 ÷ 1000 = 2.3 kW

kW = V·I·PF ÷ 1000

Formula

kW = ...

kW = 230 × 10 × 1 ÷ 1000 = 2.3 kW

single-phase

How this was calculated

  1. Identify the source: 10 A is the measured load current.
  2. Apply the single-phase formula with voltage 230 V and power factor 1.
  3. kW = V·I·PF ÷ 1000 = kW = 230 × 10 × 1 ÷ 1000 = 2.3 kW
Engineering disclaimer: kW from amps assumes a purely balanced three-phase load and a constant power factor; nameplate and measured power factor vary with loading. For motors, verify against NEC Article 430 and the manufacturer's data.
