Convert kiloelectron-volt to gigajoule
Please provide values below to convert kiloelectron-volt [keV] to gigajoule [GJ], or Convert gigajoule to kiloelectron-volt.
1 keV = 1.6022e-25 GJ. To convert kiloelectron-volt to gigajoule, multiply the value by 1.6022e-25; to go the other way, divide by it (1 GJ = 6.2415e+24 keV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 keV = 1.6022e-25 GJ
- 1 GJ = 6.2415e+24 keV
- 10 keV = 1.6022e-24 GJ
- 100 keV = 1.6022e-23 GJ
How to Convert Kiloelectron-Volt to Gigajoule

Kiloelectron-Volt
A kiloelectron-volt (keV) is a unit of energy equal to 1,000 electron-volts, commonly used in atomic and nuclear physics to measure small amounts of energy.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing energies at the atomic scale, with the prefix 'kilo' added later to denote 1,000 electron-volts, especially in high-energy physics and astrophysics.
Current Use
The keV is widely used today in fields such as X-ray spectroscopy, astrophysics, and particle physics to quantify energies of particles, photons, and nuclear processes.
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.
