What is eV to Volts Converter?
eV to Volts Calculator is an application that converts energy in the form of electron volts into electric potential, measured as volts. In physics and electrical engineering, electron volts are commonly used to denote the unit of energy primarily when dealing with atomic particles, quantum mechanics, and semiconductor physics. On the other hand, a volt denotes potential difference or electric potential energy per unit charge. The result of this will be to produce the possibility of converting eV into volts so that one can calculate electric potential in an understandable and easier way, more specially in chemistry, electronics, and particle physics in terms of the energy of particles.
You can also convert eV to Volts using the following formula if automation not works for you.
eV to Volts Conversion
Formula 1: eV to Volts Using Elementary Charge (e)
The voltage \( V \) in volts (V) is equal to the energy \( E \) in electron-volts (eV), divided by the electric charge \( Q \) in elementary charge (e):
\[ V(V) = \frac{E(\text{eV})}{Q(e)} \]
Where:
- \( V \) = Voltage in volts
- \( E(\text{eV}) \) = Energy in electron-volts
- \( Q(e) \) = Elementary charge, approximately \( 1.602 \times 10^{-19} \) coulombs
Example Calculation
If the energy \( E \) is 3.2 eV and the elementary charge \( Q \) is \( 1.602 \times 10^{-19} \) C:
\[ V = \frac{3.2}{1.602 \times 10^{-19}} \approx 2 \times 10^{19} \text{ volts} \]
Formula 2: eV to Volts Using Coulombs (C)
The voltage \( V \) in volts (V) is equal to \( 1.602176565 \times 10^{-19} \) times the energy \( E \) in electron-volts (eV), divided by the electric charge \( Q \) in coulombs (C):
\[ V(V) = \frac{1.602176565 \times 10^{-19} \times E(\text{eV})}{Q(\text{C})} \]
Where:
- \( V \) = Voltage in volts
- \( E(\text{eV}) \) = Energy in electron-volts
- \( Q(\text{C}) \) = Electric charge in coulombs
Example Calculation
If the energy \( E \) is 4 eV and the electric charge \( Q \) is \( 2 \times 10^{-19} \) C:
\[ V = \frac{1.602176565 \times 10^{-19} \times 4}{2 \times 10^{-19}} = 3.204 \text{ volts} \]

Frequently Asked Questions
Q1: Is 1 eV equal to 1 Volt?
A: No, 1 eV does not equal 1 Volt. The relationship between eV and volts depends on the charge of the particle. For a single elementary charge, the energy in eV equals the voltage.
Q2: Why is eV used instead of volts in particle physics?
A: eV is a measure of energy, which is more direct for calculating particle energies, while volts measure electric potential.
