A Hartree, denoted as E_h, is the atomic unit of energy. It's named after the British physicist Douglas Hartree. It is defined as the kinetic energy of an electron orbiting an atomic nucleus in the ground state of hydrogen. The value of one Hartree is approximately 4.359744650 x 10^-18 joules. This unit is commonly used in quantum chemistry and atomic physics to simplify calculations involving atomic-scale energies.
Definition of MicrojouleA microjoule (µJ) is a unit of energy equal to one millionth of a joule. The joule is the SI unit of energy, representing the amount needed to apply a one-newton force over one meter. In more tangible terms, a microjoule is a very small amount of energy, often used to measure the energy at microscopic scales, such as in the fields of physics, engineering, and chemistry, where precise energy measurements are crucial.

Example 1:
Convert 1 Hartree to microjoules:
1 E_h = 1 × 2,625,499.641 µJ = 2,625,499.641 µJ
Example 2:
Convert 0.1 Hartree to microjoules:
0.1 E_h = 0.1 × 2,625,499.641 µJ = 262,499.964 µJ
The concept of Hartree energy originates from Douglas Hartree's work in the early 20th century. It was developed as a natural energy unit in the field of atomic physics, particularly in quantum mechanics. Its conversion to microjoules is a modern necessity for scientists and engineers who require precise energy measurements in practical applications outside the atomic scale.
