💡 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 kWh to kW?

Use the formula: kW = kWh ÷ Hours

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.

📖 Glossary

Volt (V)

Unit of electrical potential — the 'pressure' that drives current.

Ampere (A)

Unit of electrical current — the 'flow rate' of electrons.

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.
