About Hartree
The hartree, or the Hartree energy, is the atomic unit of energy equal to 4.3597439422 × 10-18 joules (1 Eh = 4.3597439422 × 10-18 J), the SI derived unit of energy.
The Hartree energy is also equal to 4.3597439422 × 10-21 kilojoules (kJ), or 27,211.38254351886 millielectronvolts (meV), or 27.21138254351886 electronvolts (eV) or 0.02721138254351886 kiloelectronvolts (keV).
The hartree (or the Hartree energy) is usually used as a unit of energy in computational chemistry and atomic physics.
Symbol: Eh or Ha
Plural: Hartree
Also known as: Hartree energy
