What is Hartree?


The hartree (or the Hartree energy) is the atomic unit of energy equal to 4.3597439422x10-18 joules (1 Eh = 4.3597439422x10-18 J), the SI derived unit of energy. It is also equal to 4.3597439422x10-21 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.

The SI is an abbreviation for the International System of Units.
