Quick Intro: Convert Amps to KW

The Amps to kW Calculator helps convert electrical current (amps) into power (kilowatts) for single-phase and three-phase systems. This is especially useful when designing electrical circuits or sizing equipment. Input your amperage and voltage to instantly find the corresponding kW value, using the proper formulas for accurate conversion.

Formulas Used:

  • Single Phase: kW = (V × I × PF) / 1000
  • Three Phase: kW = (√3 × V × I × PF) / 1000
  • DC: kW = (V × I) / 1000
  • Note: PF = Power Factor (typically 0.8 to 1)

Frequently Asked Questions - Amps To KW Calculator:

kW = (V × I × PF) / 1000 for single phase.
Power factor (PF) is the ratio of real power to apparent power, typically between 0.8 and 1.
No, power factor is only relevant for AC circuits.
Use kW = (√3 × V × I × PF) / 1000.
Yes, it's based on standard electrical formulas.
Yes, as long as voltage and current are known.
Amps, Volts, Power Factor, and kW.
Yes, unless the load is purely resistive (PF=1).
Yes, by rearranging the formula: Amps = (kW × 1000) / (V × PF).
No, frequency is not considered in basic kW conversion.
