What does 1 therm (EC) represent in terms of energy?

1 therm (EC) is defined as 100,000 British thermal units, approximately 105.5 megajoules or 29.307 kilowatt-hours, commonly used in European energy contexts.

Why is Hartree energy used in quantum chemistry?

Hartree energy is the atomic unit of energy that provides a natural scale for electronic structure calculations and theoretical studies in atomic physics and quantum chemistry.

Can I use this conversion for everyday energy billing?

No, the therm (EC) to Hartree energy conversion translates macroscopic to atomic-scale units and is mainly relevant for scientific research rather than practical billing.
