An electron-volt (eV) is a unit of energy used in physics and chemistry — the eV to Volts Calculator converts that energy into an equivalent voltage by dividing it by a given electric charge. Enter your Energy (eV), select your Charge Unit Type (elementary charge or Coulombs), and enter your Charge Value to get the resulting Voltage in Volts along with the formula used.

To convert eV to volts, divide the energy in electron-volts by the charge. For elementary charge: V = E(eV) / Q(e). For coulombs: V = 1.602176634×10⁻¹⁹ × E(eV) / Q(C).
The formula depends on charge units. With elementary charge: V(V) = E(eV) / Q(e). With coulombs: V(V) = 1.602176634×10⁻¹⁹ × E(eV) / Q(C), where 1.602176634×10⁻¹⁹ is the elementary charge constant.
An electron-volt is a unit of energy equal to the energy gained by an electron when accelerated through a potential difference of one volt. It equals approximately 1.602×10⁻¹⁹ joules.
No, you cannot directly convert eV to volts since they represent different physical quantities. eV is energy while volts measure electric potential. You need to know the charge to perform the conversion.
Elementary charge (e) is the electric charge of a single proton or the magnitude of charge of a single electron, equal to approximately 1.602176634×10⁻¹⁹ coulombs.
This conversion is useful in physics and electronics when analyzing particle accelerators, electron guns, photoelectric effects, or any system where you know the energy of charged particles and need to find the voltage.
Elementary charge (e) is the natural unit for single particles, while coulombs (C) are used for macroscopic charges. The conversion factor between them is the elementary charge constant 1.602176634×10⁻¹⁹ C/e.
