| 1 keV | 1.602e-16 V | 1.602 × 10⁻¹⁶ V |
| 1 MeV | 1.602e-13 V | 1.602 × 10⁻¹³ V |
| 1 eV (atto) | 1.602e-37 V | – |
| 1 peV | 1.602e-28 V | – |
EV to V Formula
Use \( V = \frac{E}{e} \) where \( E \) is energy in joules, \( e = 1.60217662 \times 10^{-19} \) C (elementary charge). For eV: \( V = \frac{\text{eV value} \times 1.60217662 \times 10^{-19}}{\text{prefix factor}} \).
Steps for Electron Volts to Volts Conversion
- Multiply eV by prefix (e.g., 1e-18 for atto).
- Times \( 1.60217662 \times 10^{-19} \).
- Apply V prefix if needed.
Example: 1 eV = \( 1 \times 1.60217662 \times 10^{-19} \) V.

Common Questions
Why eV much smaller than V?
One eV equals tiny energy for single electron, yielding \(10^{-19}\) V.
Batch convert multiple eV values?
Paste comma-separated list into input for bulk electron volts to volts results.
Prefix for femtovolts?
Select femto (f) for 1e-15 eV to match femtovolt outputs.
