The electron volt (eV) is the energy gained by a single electron accelerating through a potential difference of one volt, equal to approximately 1.602 × 10⁻¹⁹ joules. It was formally adopted as a unit by the IEC in 1930.
Electron volts are the standard energy unit in atomic physics, particle physics, and semiconductor engineering. Chemical bond energies are a few eV; X-ray photons are kiloelectron volts (keV); particle accelerators measure GeV and TeV.
Interesting fact: The Large Hadron Collider accelerates protons to 6.8 TeV (6.8 × 10¹² eV). Visible light photons have energies of 1.8–3.1 eV. The rest mass energy of an electron is 511 keV.
The erg is the unit of energy in the CGS (centimeter-gram-second) system, equal to exactly 10⁻⁷ joules. It was defined by the British Association for the Advancement of Science in 1882 as the work done by a force of one dyne over one centimeter.
Ergs were widely used in 19th and early 20th century physics before SI standardization. They remain in use in astrophysics (stellar luminosities in erg/s) and some older scientific literature.
Interesting fact: The Sun radiates about 3.8 × 10³³ ergs per second. A mosquito in flight exerts about 100 ergs of energy per wingbeat. One joule = 10,000,000 ergs exactly.
Converting electron volt to erg is common across energy, nutrition, engineering, and science. Different sectors use different energy units — joules in physics, kcal in nutrition, kWh in electricity, and BTU in HVAC — making accurate conversion essential for cross-disciplinary work and international comparisons.
