Volts to eV Calculator

What this calculator does

The Volts to eV Calculator converts Volts into eV using standard electrical relationships. Enter Voltage, Number of Electrons to compute results for real-world electrical scenarios. Use it for quick checks, comparisons, and documentation while planning.

Inputs explained

  • Voltage: Electrical potential difference in volts (V).
  • Number of Electrons: Value used by the calculator.

How it works / Method

The calculator applies the listed formulas to the values you enter and then formats the result in standard units. For AC calculations, power factor and phase selection adjust real power to match typical loads.

Formulas used

  • eV = V x q / 1.602x10⁻¹⁹

Units: V in volts (V)

About eV

1 eV = energy of 1 electron through 1V
Common in semiconductor physics

Step-by-step example

Scenario: Convert 5V potential for an electron.

Formula: eV = V x q / 1.602x10⁻¹⁹

  1. For single electron: eV = V
  2. eV = 5 electron-volts

Result: 5 eV

Use cases

  • Convert between common electrical units during quick checks.
  • Cross-check nameplate ratings against measured inputs.
  • Compare DC, single-phase, and three-phase scenarios.
  • Estimate loads for planning and documentation.

Assumptions & limitations

  • Results are estimates and may be rounded; small differences are expected.
  • Inputs assume steady-state values; transient and surge effects are not modeled.
  • Voltage can vary by supply, load, and location; use measured values when possible.
  • Power factor varies by load type; use a realistic value for inductive equipment.
  • Wiring rules and safety codes vary by jurisdiction; consult a licensed electrician for installation decisions.
