How to Convert Electron Volts to Joules
Converting electron volts to joules is essential in particle physics and quantum mechanics. One electron volt equals approximately 1.60218 x 10^-19 joules.
To convert eV to joules, multiply the eV value by 1.60218 x 10^-19. For example, 1,000,000 eV x 1.60218 x 10^-19 = 1.60218 x 10^-13 J. This tiny energy scale is appropriate for atomic and subatomic processes.
Electron volts are convenient for atomic-scale energies where joules would be impractically small.
Quick Tips
- 1 mile = 1.609 km (miles are bigger)
- 1 kg = 2.205 lbs (roughly double + 10%)
- Temperature: (°F - 32) × 5/9 = °C
