Convert hartree energy to j
Hartree Energy
The hartree (symbol: Eh) is the atomic unit of energy, equal to approximately 4.3597 × 10⁻¹⁸ joules (27.211 eV). It represents twice the ionisation energy of a hydrogen atom in its ground state and is the natural energy unit of atomic and molecular physics calculations. The hartree is named after Douglas Hartree, pioneer of the self-consistent field method in quantum chemistry.
Joule
The joule (/dʒaʊ,dʒuːljawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m). It is also the energy dissipated as heat when an electric current of one ampere passes through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule (1818–1889).
