Convert Electronvolt to Joule
Unit definitions
Electronvolt
An electronvolt is the kinetic energy gained by an electron accelerating through a potential difference of one volt.
Joule
The joule is the SI unit of energy. It is defined as the work done when a force of one newton is applied over a distance of one meter.
How to convert Electronvolt to Joule
$$\text{Energy}_{\text{J}} = \text{Energy}_{\text{eV}} \cdot 1.602176462e - 19$$
Examples
Example 1
Convert $45.0\ \text{eV}$ to $\text{J}$.
$$\text{Energy}_{\text{J}} = 45.0 \cdot 1.602176462e - 19$$
$$\text{Energy}_{\text{J}} = 0.000000000000000007209794079$$
$$\therefore \ 45.0\ \text{eV} = 0.000000000000000007209794079 \ \text{J}$$
Example 2
Convert $60.0\ \text{eV}$ to $\text{J}$.
$$\text{Energy}_{\text{J}} = 60.0 \cdot 1.602176462e - 19$$
$$\text{Energy}_{\text{J}} = 0.000000000000000009613058772$$
$$\therefore \ 60.0\ \text{eV} = 0.000000000000000009613058772 \ \text{J}$$
Example 3
Convert $110.0\ \text{eV}$ to $\text{J}$.
$$\text{Energy}_{\text{J}} = 110.0 \cdot 1.602176462e - 19$$
$$\text{Energy}_{\text{J}} = 0.000000000000000017623941082$$
$$\therefore \ 110.0\ \text{eV} = 0.000000000000000017623941082 \ \text{J}$$
Example 4
Convert $140.0\ \text{eV}$ to $\text{J}$.
$$\text{Energy}_{\text{J}} = 140.0 \cdot 1.602176462e - 19$$
$$\text{Energy}_{\text{J}} = 0.000000000000000022430470468$$
$$\therefore \ 140.0\ \text{eV} = 0.000000000000000022430470468 \ \text{J}$$
Example 5
Convert $190.0\ \text{eV}$ to $\text{J}$.
$$\text{Energy}_{\text{J}} = 190.0 \cdot 1.602176462e - 19$$
$$\text{Energy}_{\text{J}} = 0.000000000000000030441352778$$
$$\therefore \ 190.0\ \text{eV} = 0.000000000000000030441352778 \ \text{J}$$
