31 Ιουλ 2024 · 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.
Kilojoules per mole (kJ/mol) A Joule, J, is the SI unit of energy and is defined as one kg.m 2 /s 2. The prefix "kilo" means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence "per mole".
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.
