What is Hartree energy used for?

Hartree energy is used primarily in atomic physics and quantum chemistry to report total electronic energies and energy differences in atoms and molecules.

Why convert Hartree energy to foot-pounds?

Converting to foot-pounds allows scientists and engineers to relate atomic-scale energy values to mechanical energies familiar in engineering and ballistics.

Is foot-pound the same as torque?

Foot-pound can represent energy or torque since both share the same dimensional units, commonly used in mechanical and automotive fields.
