The electron-volts to volts calculator is a useful tool for converting energy values measured in electron-volts (eV) to their corresponding voltage values in volts. To use the calculator, simply enter the energy value in eV and select the charge unit type from the dropdown menu. Depending on the charge unit type selected, users will need to enter the corresponding charge value in either elementary charge units or coulombs. Once all required fields are filled, click the “Calculate” button to obtain the corresponding voltage value in volts. The “Reset” button can be used to clear all fields and start over.

eV to Volts Calculation with Elementary Charge
Electric potential difference, denoted as voltage (V), can be expressed in terms of energy (E) and electric charge (Q). Specifically, voltage equals the quotient of energy measured in electron-volts (eV) and electric charge measured in elementary charge or proton/electron charge (e).
V(V) = E(eV) / Q(e)
Example
What amount of voltage, measured in volts, is required to power an electrical circuit that consumes 1000 electron-volts of energy and has a charge flow of 40 electron charges?
V = 1000eV / 40e = 25 V
eV to Volts to Calculation with Coulombs
The voltage V in volts (V) is equal to 1.602176634×10−19 times the energy E in electron-volts (eV), divided by the electrical charge Q in coulombs (C):
V(V) = 1.602176634×10−19 × E(eV) / Q(C)
