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 (Th)
The Btu (th), or British thermal unit (th), is a unit of energy used primarily in the United States to measure heat content, equivalent to the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.
History/Origin
The Btu (th) originated from the British thermal unit, a traditional unit of heat in the British Imperial system, and has been used historically in heating, cooling, and energy industries to quantify energy content and heat transfer.
Current Use
Today, the Btu (th) is mainly used in the energy sector, particularly in heating and cooling systems, natural gas billing, and energy content measurement, especially within the United States.
