Conversion Formula
The formula to convert electron volts (ev) to joules (J) is straightforward: J = ev × 1.602176634 × 10-19. This works because the electron volt is a unit defined as the energy gained by an electron when moving through a potential difference of one volt. Multiplying the number of ev by this constant converts the energy into joules, the SI unit of energy. For example, converting 11.6 ev involves multiplying 11.6 by 1.602176634 × 10-19, resulting in approximately 1.8582 × 10-18 joules.

Conversion Definitions
ev
Electron volt (ev) is a unit of energy defined as the energy gained or lost by an electron when it moves across a potential difference of one volt, equivalent to 1.602176634 × 10-19 joules, used mainly in atomic and particle physics.
Joules
Joules (J) is the SI unit of energy, representing the work done when a force of one newton moves an object one meter. It measures energy, work, and heat, and is used across scientific disciplines for quantifying energy amounts in various systems.
Conversion FAQs
Why is the electron volt a convenient unit for atomic physics?
The electron volt simplifies energy calculations at atomic scales because energies involved are extremely small. It allows scientists to work with manageable numbers instead of very tiny joules, making it easier to interpret and compare energies in particles and atoms.
How precise is the conversion from ev to joules?
The conversion uses a fixed constant of 1.602176634 × 10-19 joules per ev, which is an exact value in SI units, ensuring high accuracy. Minor differences only occur due to rounding in calculations or measurement precision in specific contexts.
Can I convert large energy values from ev to joules directly?
Yes, you multiply the number of ev by the constant 1.602176634 × 10-19. For very large energies, scientific notation is recommended to keep the numbers manageable and avoid errors in manual calculations.
