A joule (J) is the SI derived unit of energy, work, and heat, defined as the energy transferred when a force of one newton moves an object one meter.

What is Hartree energy used for?

Hartree energy is used as an atomic unit of energy in atomic physics and quantum chemistry, helping report electronic energies and reaction details.

Why do conversion results yield very large numbers?

Because 1 joule equals approximately 229371044869060000 Hartree energy, converting joules to Hartree results in very large numerical values.
