# Volts to electron-volts calculator

Convert voltage in volts (V) to energy in electron-volts (eV). Ideal for understanding the energy levels of particles in electronic systems. Obtain an estimation of electron-volts from volts using this practical online tool.

## What is Volts to electron-volts calculator

To convert volts (V) to electron-volts (eV), you can use the conversion factor:

1 volt = 6.242 × 10^18 electron-volts

To convert from volts to electron-volts, simply multiply the voltage by the conversion factor.

For example, if you have a voltage of 10 volts (V), you can convert it to electron-volts as follows:

Electron-volts (eV) = 10 V * 6.242 × 10^18 Electron-volts (eV) ≈ 6.242 × 10^19 eV

In this example, the voltage of 10 volts is approximately equal to 6.242 × 10^19 electron-volts.

Electron-volts (eV) is a unit commonly used in physics and represents the energy gained or lost by an electron when it moves across an electric potential difference of one volt.

## 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)}

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*_{(V)}* *×* Q*_{(C)} / 1.602176565×10^{-19}

## Volts to electron-volts calculator Example

Here's an example table that demonstrates the conversion of volts to electron-volts:

Voltage (V) | Energy (eV) |
---|---|

12V | 1.92 × 10^(-18) eV |

24V | 3.84 × 10^(-18) eV |

9V | 1.44 × 10^(-18) eV |

6V | 9.6 × 10^(-19) eV |

15V | 2.4 × 10^(-18) eV |

To perform the conversion for a given voltage, multiply the voltage value by 1.6 × 10^-19. For instance, if you have a voltage of 12V:

Energy (eV) = 12V * (1.6 × 10^-19) Energy (eV) = 1.92 × 10^(-18) eV

Therefore, for a voltage of 12V, the equivalent energy in electron-volts is approximately 1.92 × 10^(-18) eV.

Keep in mind that electron-volts are a convenient unit for measuring small energies on the atomic and subatomic scale.
