How many joules are in an electronvolt?
One electronvolt is exactly 1.602176634×10⁻¹⁹ joules (SI definition).
Detailed answer
The electronvolt is the energy gained by one elementary charge crossing 1 V. Since 2019, the joule value is exact via the fixed elementary charge.
Relationship context
Particle physics, band gaps, and chemistry bond energies often use eV or keV alongside joules.
