- 💡Always verify calculated values against local electrical codes (NEC, IEC).
❓ Frequently Asked Questions
How do I convert Volts to Joules?
Use the formula: Joules = Volts × Coulombs
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.
