What does Btu (th) represent?

Btu (th) or thermochemical British thermal unit is a traditional energy unit representing the heat needed to raise one pound of water by one degree Fahrenheit.

Where is Hartree energy commonly used?

Hartree energy is used in atomic physics and quantum chemistry to describe electronic energies of atoms and molecules.

Why are the converted values so large?

Because Btu (th) represents macroscopic thermal energy and Hartree energy is an atomic unit much smaller in scale, conversions result in extremely large numbers.
