What is Hartree energy used for?

Hartree energy is an atomic unit used primarily in quantum chemistry to report total electronic energies of atoms and molecules and to express reaction energy differences.

What does fuel oil equivalent per barrel represent?

It represents the energy content in one US barrel of fuel oil, which is used to express petroleum volumes on an energy basis rather than simply volume.

Why is the conversion from Hartree energy to fuel oil equivalent so small?

Because Hartree energy is an extremely small unit on the atomic scale, its equivalent in large-scale fuel oil energy units results in very tiny numerical values.
