Convert electron-volt to kiloelectron-volt
Please provide values below to convert electron-volt [eV] to kiloelectron-volt [keV], or Convert kiloelectron-volt to electron-volt.
1 eV = 0.001 keV. To convert electron-volt to kiloelectron-volt, multiply the value by 0.001; to go the other way, divide by it (1 keV = 1000 eV). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 eV = 0.001 keV
- 1 keV = 1000 eV
- 10 eV = 0.01 keV
- 100 eV = 0.1 keV
How to Convert Electron-Volt to Kiloelectron-Volt
1 eV = 0.001 keV
Example: convert 15 eV to keV:
15 eV = 15 × 0.001 keV = 0.015 keV

Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
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.
Frequently Asked Questions
What is 1 electron-volt in kiloelectron-volt?
1 electron-volt (eV) = 0.001 kiloelectron-volt (keV).
How do you convert electron-volt to kiloelectron-volt?
Multiply the electron-volt value by 0.001. For example, 25 eV × 0.001 = 0.025 keV.
What is 10 electron-volt in kiloelectron-volt?
10 eV = 0.01 keV.
Which unit is larger, the electron-volt or the kiloelectron-volt?
The kiloelectron-volt is the larger unit: 1 eV equals only 0.001 keV.
