Table of coefficients for energy unit conversion between atomic unit (hartree), joule (J), electron volt (eV), cm-1, kJ/mol, and kcal/mol.
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. [1]

Conversion of eV to Joules (1) Answer = [1.22 × 10–7 m] (1) Example of answer. E = hf and c = fλ E = hc/λ. 10. 7. [5] 2. (a) Diffraction is the change in direction of wave or shape or wavefront (1) when the wave passes an obstacle or gap (1) 2. (b) The energy of the wave is concentrated into a photon (1)
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.
Energy converter tool adapted from Colby College. Enter your energy value in the box with the appropriate units, then press "tab" or click outside of the input box. Hartrees (Eh) eV. kJ/mol. kcal/mol.
