What is Hartree energy used for?

Hartree energy is the atomic unit of energy used mainly in atomic physics and quantum chemistry to report electronic energies and energy differences.

Why convert Hartree energy to watt-hour?

This conversion helps translate atomic-scale energy values into practical units like watt-hours, linking microscopic calculations with real-world energy contexts.

Is this conversion useful for everyday energy measurements?

No, because Hartree energy values are exceedingly small, conversion results are mostly meaningful in theoretical or research applications.
