What is Hartree energy used for?

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

Why convert Hartree energy to therm (US)?

Converting Hartree energy to therm (US) helps relate atomic-scale quantum energy measurements to practical heating and natural gas energy units used in industry.

Is this conversion suitable for everyday energy billing?

No, due to the extremely small magnitude of Hartree energy, this conversion is mainly for theoretical and scientific contexts rather than routine billing.
