It is a conversion calculator used to convert the electrical voltage in volts (V) to the energy in electron volts (eV). Volts cannot be converted directly to electron volts, but you can calculate electron volts from elementary coulombs and volts. The reason is that the two units have different quantities thus the conversion cannot be fulfilled.

Volts to eV calculation with elementary charge

The energy E in electron-volts (eV) is equal to the voltage V in volts (V), times the electric charge Q in elementary charge or proton/electron charge (e):

E_(eV) = V_(V) × Q_(e)

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_(V) × Q_(C) / 1.602176565×10^-19
