Instant free online tool for electron-volt to joule conversion or vice versa. The electron-volt [eV] to joule [J] conversion table and conversion steps are also listed. Also, explore tools to convert electron-volt or joule to other energy units or learn more about energy conversions.
When used as a unit of energy, the numerical value of 1 eV in joules (symbol J) is equal to the numerical value of the charge of an electron in coulombs (symbol C). Under the 2019 revision of the SI , this sets 1 eV equal to the exact value 1.602 176 634 × 10 −19 J .
Typical units for ionization energies are kilojoules/mole (kJ/mol) or electron volts (eV): \[1\; eV/atom = 96.49\; kJ/mol \nonumber \] If an atom possesses more than one electron, the amount of energy needed to remove successive electrons increases steadily.
Table of coefficients for energy unit conversion between atomic unit (hartree), joule (J), electron volt (eV), cm-1, kJ/mol, and kcal/mol.
7 Δεκ 2023 · Divide joules by 1.6 × 10 –19 to get the equivalent energy in electronvolts. Converting between electronvolts and joules. Sometimes, units of MeV or GeV are used. These are given by: 1 MeV = 1 × 106 eV = 1.6 × 10–13 J. 1 GeV = 1 × 109 eV = 1.6 × 10–10 J.
This is Omni's wavelength to energy calculator, a tool that instantly calculates a photon's energy from its wavelength. By using Planck's equation, this tool will help you determine a photon's energy in joules (J), electronvolts (eV), or its multiples.
