What is a pound-force inch (lbf·in)?

It is a unit of energy measuring work done by a one pound-force acting through a one-inch displacement, used in US customary mechanical applications.

Why convert pound-force inch to Hartree energy?

To relate macroscopic mechanical energy measurements to atomic-scale energies used in quantum chemistry and atomic physics.

Are values in Hartree energy practical for everyday engineering?

No, due to enormous magnitudes, Hartree energy values from typical mechanical units are mainly of theoretical interest.
