About this calculator
Overview
An electron volt (eV) is a unit of energy equal to the amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of one volt.
💡
Pro Tips
Formula: E (eV) = V * q (in elementary charges)
If q is 1 (single electron), Energy in eV is numerically equal to Voltage.
1 eV ≈ 1.602 × 10^-19 Joules.

Fun Facts
"The electron volt is widely used in solid-state physics and particle physics."
"Visible light photons have energies between 1.8 eV (red) and 3.1 eV (violet)."
"LHC (Large Hadron Collider) accelerates protons to energies of 6.5 Tera-electronVolts (TeV)."
