Electronvolts (eV) to Ergs (erg) Conversion
Electronvolts
The electronvolt (eV) is a unit of energy equal to exactly 1.602176634 × 10⁻¹⁹ joules, defined as the kinetic energy gained by a single electron accelerated through a potential difference of one volt. It is the standard unit in particle physics, atomic physics, and solid-state physics. Visible light photons carry 1.8–3.1 eV of energy; X-ray photons carry 100 eV to 100 keV; the proton beams at CERN's LHC reach 6.5 teraelectronvolts (TeV).
Ergs
The erg is a unit of energy in the CGS (centimetre-gram-second) system, equal to exactly 10⁻⁷ joules. The word derives from the Greek ergon (work). Though largely superseded by the joule in modern science, the erg persists in astrophysics — stellar luminosities and gamma-ray burst energies are sometimes expressed in ergs — and in classical physics texts. One erg is approximately the energy required to move a mosquito by 1 cm. The total energy released by the Sun per second is approximately 3.8 × 10³³ ergs.
