Inch-Pound
The inch-pound (in·lbf) is a unit of torque or energy, representing the force of one pound applied at the end of a one-inch lever arm.
History/Origin
The inch-pound has been used primarily in the United States and other countries that employ imperial units, originating from the traditional use of inches and pounds in mechanical and engineering contexts, with its formal recognition dating back to the 19th century.
Current Use
It is commonly used in engineering, automotive, and mechanical applications to measure torque and energy, especially in contexts where imperial units are standard.
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.
