What is Hartree energy used for?

Hartree energy is primarily used in atomic physics and quantum chemistry for reporting atomic and molecular electronic energies, reaction energies, and simplifying theoretical calculations by setting fundamental constants to unity.

Why convert Hartree energy to gigaton?

Converting Hartree energy to gigaton helps relate atomic-scale energy values to extraordinarily large energy releases such as nuclear explosions or planetary impacts, facilitating comparisons across vastly different energy scales.

Is this conversion useful for everyday energy measurements?

No, because the scale difference is enormous, converted values are extremely small, making this conversion mostly relevant for theoretical and comparative contexts rather than routine measurements.
