How to convert electron-volts to volts

How to convert energy in electron-volts (eV) to electrical voltage in volts (V).

You can calculate volts from electron-volts and elementary charge or coulombs, but you can't convert electron-volts to volts since electron-volt and volt units represent different quantities.

eV to volts calculation with elementary charge

So 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 or proton/electron charge (e):

V(V) = E(eV) / Q(e)

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

So

volt = electronvolt / elementary charge

or

V = eV / e

Example 1

What is the voltage supply in volts of an electrical circuit with energy consumption of 800 electron-volts and charge flow of 50 electron charges?

V = 800eV / 50e = 16V

Example 2

What is the voltage supply in volts of an electrical circuit with energy consumption of 500 electron-volts and charge flow of 50 electron charges?

V = 500eV / 50e = 10V

Example 3

What is the voltage supply in volts of an electrical circuit with energy consumption of 1000 electron-volts and charge flow of 50 electron charges?

V = 1000eV / 50e = 20V

eV to volts to calculation with coulombs

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

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

So

volt = 1.602176565×10-19 × electronvolt / coulomb

or

V = 1.602176565×10-19 × eV / C

Example 1

What is the voltage supply in volts of an electrical circuit with energy consumption of 800 electron-volts and charge flow of 3 coulombs?

V = 1.602176565×10-19 × 800eV / 3C = 4.2724×10-17V

Example 2

What is the voltage supply in volts of an electrical circuit with energy consumption of 500 electron-volts and charge flow of 3 coulombs?

V = 1.602176565×10-19 × 500eV / 3C = 2.6702×10-17V

Example 3

What is the voltage supply in volts of an electrical circuit with energy consumption of 1000 electron-volts and charge flow of 3 coulombs?

V = 1.602176565×10-19 × 1000eV / 3C = 5.3405×10-17V

FAQ

How do you convert eV to volts?

How to calculate electron volts from elementary charge. Our volt to electron volt calculator uses the following formula: eV = V × e.

How many electrons are in a volt?

We already know that 1 volt is an EMF of 6.24 X 1018 electrons.

What is the relation between volt and electron volt?

1 electron volt is the energy change that takes place when a charge equal to 1 electron (1.6×10-19C) is moved through a potential difference of 1 volt.

What is the formula for electron-volts?

Note that 1 eV is the kinetic energy acquired by an electron or a proton with a potential difference of 1 volt. The formula for energy in the form of charge and potential difference is E = QV. So 1 eV = (1.6 x 10^-19 Coulomb)x(1 Volt) = 1.6 x 10^-19 Joule.
