Convert kiloelectron-volt to attojoule
Please provide values below to convert kiloelectron-volt [keV] to attojoule [aJ], or Convert attojoule to kiloelectron-volt.
1 keV = 160.2176634 aJ. To convert kiloelectron-volt to attojoule, multiply the value by 160.2176634; to go the other way, divide by it (1 aJ = 0.00624150907446 keV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
