kW to Volts Calculator

Enter the electrical values below to calculate the result.

The real power in kilowatts (kW).
The electrical current in amperes (A).
Select whether the system is DC, AC Single-Phase, or AC Three-Phase.
The ratio of real power to apparent power (efficiency, 0.8 is typical).
Calculation Formula
Volts = (kW × 1000) / (Amps × PF × Phase Mult)
Voltage equals power divided by current. Phase Multipliers: DC = 1, AC 1-Phase = 1, AC 3-Phase Line-to-Line = 1.732, AC 3-Phase Line-to-Neutral = 3.

Calculated Result

0.00 V

Calculated electrical potential in volts.

💡 Tips

  • 💡Always enter the correct voltage (120V, 220V, 240V, 480V etc.) for your system.
  • 💡For 3-phase systems, use the 3-phase formula option if available.
  • 💡Power factor is typically 0.8–0.95 — use 0.85 if unsure.
  • 💡Always verify calculated values against local electrical codes (NEC, IEC).

❓ Frequently Asked Questions

How do I convert kW to Volts?
Use the formula: Volts = (kW × 1,000) ÷ Amps
What voltage should I use?
Use your system voltage — 120V or 240V for US residential, 230V for UK/EU.
What is power factor?
Power factor (0–1) represents how efficiently power is used. Use 0.8 as a safe default.
Is the calculator accurate?
Yes, it uses standard electrical engineering formulas.
Is it free?
Yes, completely free.
Should I rely on this for wiring?
Always verify with a licensed electrician before making wiring decisions.
Does it support 3-phase?
Yes, select the 3-phase option if your system uses three-phase power.
What is the difference between kVA and kW?
kW is real power; kVA is apparent power. kW = kVA × Power Factor.

⚠️ Common Mistakes to Avoid

  • ⚠️Using the wrong voltage (120V vs 240V) — this halves or doubles results.
  • ⚠️Ignoring power factor for AC circuits — can cause undersized equipment.
  • ⚠️Confusing single-phase and three-phase formulas.
  • ⚠️Using DC formulas for AC circuits without power factor adjustment.

Watt (W)
Unit of real power — energy per unit time.
kVA
Kilo-Volt-Amperes — unit of apparent power in AC systems.
Power Factor
Ratio of real power to apparent power (0 to 1).
kWh
Kilowatt-hour — unit of energy consumed over time.
