## How to convert volts to electron-volts?

charge or proton/electron charge(e).

**E(eV) = V(in volts) * Q(e)**

The elementary charge is the electric charge of 1 electron with the e symbol.

Volts to eV calculation with coulombs

The energy E in electron-volts (eV) is equal to the voltage V in volts (V), times the electrical charge

Q in coulombs (C) divided by 1.602176565*10-19.

**E(eV) = V(in Volts) * Q(C)/1.602176565*10-19**

**Example#1**

What is the energy in electron-volts that is consumed in an electrical circuit with voltage supply of 20 volts and charge flow of 40 electron charges?

E = 20V × 40e = 800eV

### Volts to eV calculation with coulombs

The energy E in electron-volts (eV) is equal to the voltage V in volts (V), times the electrical charge Q in coulombs (C) divided by 1.602176565×10-19:

**E(eV) = V(in Volts) × Q(C) / 1.602176565×10-19**

So

**electronvolt = volt × coulomb / 1.602176565×10-19 or eV = V × C / 1.602176565×10-19**

**Example#2**

What is the energy in electron-volts that is consumed in an electrical circuit with voltage supply of 20 volts and charge flow of 2 coulombs?

E = 20V × 2C / 1.602176565×10-19 = 2.4966×1020eV)copy

**The electron volt:**A unit for measuring the energy of subatomic parties; the energy equal to that attained by an electron.moving through a potential difference of one volt. Equivalent to 1.6022*10-19Joules.

**volt :** A volt is a unit to measure the force of electric current.
