Why does the energy content in fuel oil equivalent vary?

Because it depends on the specific grade and density of the fuel oil, which influences its exact energy content.

What is the Hartree energy used for?

It serves as the atomic unit of energy in atomic physics and quantum chemistry, common for electronic structure calculations.

Is this conversion suitable for everyday engineering use?

No, this conversion mainly applies to scientific and theoretical fields rather than practical engineering measurements.
