Convert gigajoule to Hartree energy
Please provide values below to convert gigajoule [GJ] to Hartree energy [Eh], or Convert Hartree energy to gigajoule.
1 GJ = 2.2937e+26 Eh. To convert gigajoule to Hartree energy, multiply the value by 2.2937e+26; to go the other way, divide by it (1 Eh = 4.3597e-27 GJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 GJ = 2.2937e+26 Eh
- 1 Eh = 4.3597e-27 GJ
- 10 GJ = 2.2937e+27 Eh
- 100 GJ = 2.2937e+28 Eh
How to Convert Gigajoule to Hartree Energy

Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
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.
