What is Hartree energy used for?

Hartree energy is the atomic unit of energy used mainly in atomic physics and quantum chemistry for electronic structure calculations and energy differences.

Why convert Hartree energy to kiloelectron-volt?

Converting to kiloelectron-volt (keV) facilitates comparison with energies used in atomic, nuclear, and radiation physics, such as those involving photons and particles.

Does the conversion consider measurement uncertainties?

No, the conversion assumes ideal unit definitions and does not account for potential measurement uncertainties or contextual differences.
