Amps To KW Calculator
Use this Amps to kW calculator to convert electrical current (A) to kilowatts (kW) for single or three-phase systems. Accurate, fast, and easy to use.

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:
What is the formula to convert amps to kW?
kW = (V × I × PF) / 1000 for single phase.
What is Power Factor?
Power factor (PF) is the ratio of real power to apparent power, typically between 0.8 and 1.
Do I need PF for DC circuits?
No, power factor is only relevant for AC circuits.
How to convert 3-phase amps to kW?
Use kW = (√3 × V × I × PF) / 1000.
Is the calculator accurate for industrial use?
Yes, it's based on standard electrical formulas.
Can I use this for solar systems?
Yes, as long as voltage and current are known.
What units does this calculator support?
Amps, Volts, Power Factor, and kW.
Is power factor required for single-phase?
Yes, unless the load is purely resistive (PF=1).
Can I calculate from kW to Amps?
Yes, by rearranging the formula: Amps = (kW × 1000) / (V × PF).
Does frequency affect this calculation?
No, frequency is not considered in basic kW conversion.
