Convert rydberg energy to j
Rydberg Energy
The Rydberg energy (symbol: Ry) is a unit of energy equal to half a hartree, approximately 2.1799 × 10⁻¹⁸ joules (13.606 eV). It corresponds to the binding energy of the electron in the ground state of the hydrogen atom and arises naturally from the Rydberg constant used in atomic spectroscopy. The Rydberg energy is the standard energy unit in condensed matter physics and solid-state electronic structure calculations.
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).
