What are Hartree and Kilojoule

The Hartree, also known as the Hartree energy (E_h), is a unit of energy named after the British physicist Douglas Hartree. It is a physical constant used primarily in quantum chemistry and atomic physics to express the energies of electrons in atoms. One Hartree is defined as the kinetic energy of an electron in an unexcited hydrogen atom, and its value is approximately 4.359744650×10^-18 joules.

A kilojoule (kJ) is a unit of energy in the International System of Units (SI). It is equivalent to 1,000 joules, the standard unit of energy. The kilojoule is commonly used in various fields such as nutrition, physics, and engineering. It is a measure of the amount of work performed, heat transferred, or energy consumed. One kilojoule is approximately the amount of energy required to lift a one-kilogram mass to a height of ten meters against Earth's gravity.

History of Hartree and Kilojoule

A brief history of the Hartree Energy to Kilojoule conversion traces back to the early 20th century with the establishment of quantum mechanics. As atomic and molecular physics advanced, the need for a practical unit to express atomic-scale energies emerged. The Hartree was adopted, and its conversion to kilojoules became a standard practice for scientists to relate quantum energy levels to macroscopic energy units.
