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.
