Conversion Formula
The conversion formula from electronvolts to joules is: Joules = eV × 1.6021765 × 10-19. This works because one electronvolt is defined as the amount of kinetic energy gained or lost by an electron when it moves through an electric potential difference of one volt. Multiplying by this factor converts the energy from eV to joules, the SI unit. For example, converting 1.6 eV involves multiplying 1.6 by 1.6021765 × 10-19, resulting in 2.5616 × 10-19 joules.
Conversion Example
- Convert 2.0 eV:
- Multiply 2.0 by 1.6021765 × 10-19:
- 2.0 × 1.6021765 × 10-19 = 3.204353 × 10-19 joules.
- Convert 0.5 eV:
- Multiply 0.5 by 1.6021765 × 10-19:
- 0.5 × 1.6021765 × 10-19 = 8.0108825 × 10-20 joules.
- Convert 10 eV:
- Multiply 10 by 1.6021765 × 10-19:
- 10 × 1.6021765 × 10-19 = 1.6021765 × 10-18 joules.
