Discover the simplicity of converting Eh to aJ using our precise Hartree Energy to Attojoule Converter, curated by Newtum to meet your scientific conversion needs.
The Hartree, symbolized as Eh, is a unit of energy specifically used in the field of atomic physics. It is named after the British physicist Douglas Hartree. This unit is part of the atomic units (au) system and is defined as the kinetic energy of an electron orbiting the nucleus of an atom in its ground state. Its value is approximately 4.35974434 x 10^-18 joules. The Hartree is essential for calculations involving the Schrödinger equation and quantum mechanics.
Definition of AttojouleThe attojoule, abbreviated as aJ, is a minuscule unit of energy in the International System of Units (SI), equal to 10^-18 joules. This unit is often used in the realms of physics and chemistry to express very small amounts of energy typical at the atomic or subatomic levels. The prefix 'atto' is derived from the Danish word 'atten,' meaning eighteen. The attojoule's small magnitude allows for precise measurements in quantum physics, nanotechnology, and related fields.
