eV to Volts Calculator

Enter the electrical values below to calculate the result.

Calculation Formula

Volts = Energy (eV) / Charge (e)

Calculates voltage. Since 1 electron-volt is the energy gained by 1 elementary charge moving across 1 volt, V = eV / charge (e).

Calculated Result

0.00 V

Calculated voltage in volts.

❓ Frequently Asked Questions

How do I convert eV to Volts?

Use the formula: V = eV ÷ Elementary Charge (1.602×10⁻¹⁹ C)

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.

About eV to Volts Calculator

Convert electron-volts to volts. Electron-volts (eV) represent quantum levels of kinetic energy gained by a single electron. If charge is equal to one elementary unit (e.g. one electron), the numerical voltage is identical to the energy in eV.
