Amps to kW Calculator — ChiefEngineer.in

Convert current to real power in kW for DC, single-phase or three-phase AC.

Reset

Formula

PkW = VI/1000 (DC)
PkW = VI·PF/1000 (1φ)
PkW = √3·VLIL·PF/1000 (3φ)

Variables

  • V — voltage (V)
  • I — current (A)
  • PF — power factor
  • VL — line voltage

Worked Example

Input: 10 A, 230 V, PF 0.9, single-phase

Result: ≈ 2.07 kW

Assumptions & Notes

Balanced load assumption for three-phase. Power factor is taken as 1 for DC.
