Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
Therm (Ec)
The therm (EC) is a unit of energy used primarily in the measurement of natural gas and heating energy, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm originated in the early 19th century as a practical unit for measuring large quantities of heat energy, especially in the gas industry, and has been standardized in various regions for energy billing and calculations.
Current Use
Today, the therm (EC) is used mainly in the natural gas industry and energy sectors to quantify heat energy consumption, although it has largely been supplemented or replaced by SI units like joules and kilowatt-hours in many regions.
