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.
Btu (It)
The Btu (IT) is a unit of energy used to measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit, based on the International Table (IT) standards.
History/Origin
The Btu (IT) originated from the British thermal unit, adapted for international standards to provide a consistent measurement of heat energy, particularly in engineering and thermodynamics contexts.
Current Use
The Btu (IT) is primarily used in the energy industry, including heating, cooling, and power generation, to quantify energy content and efficiency in systems adhering to international standards.
