What is Hartree energy used for?

Hartree energy serves as the atomic unit of energy in atomic physics and quantum chemistry, mainly used to report electronic energies and energy differences in theoretical studies.

Why convert Hartree energy to kilogram-force meters?

The conversion links quantum chemistry energy units to classical mechanical work units, aiding comparison or integration of scientific data with historical engineering references.

Is kilogram-force meter an SI unit?

No, kilogram-force meter is a non-SI, historical unit of energy used where force was expressed in kilogram-force rather than newtons.
