How many keV in 1 eV? The answer is 0.001. We assume you are converting between kiloelectronvolt and electronvolt. You can view more details on each measurement unit: keV or eV The SI derived unit for energy is the joule. 1 joule is equal to 6.2415064799632E+15 keV, or 6.2415064799632E+18 eV. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between kiloelectronvolts and electronvolts. Type in your own numbers in the form to convert the units!
1 keV to eV = 1000 eV
2 keV to eV = 2000 eV
3 keV to eV = 3000 eV
4 keV to eV = 4000 eV
5 keV to eV = 5000 eV
6 keV to eV = 6000 eV
7 keV to eV = 7000 eV
8 keV to eV = 8000 eV
9 keV to eV = 9000 eV
10 keV to eV = 10000 eV
You can do the reverse unit conversion from eV to keV, or enter any two units below:
The SI prefix "kilo" represents a factor of 103, or in exponential notation, 1E3.
So 1 kiloelectronvolt = 103 .
In physics, the electron volt (eV) is a unit of energy. By definition, it is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electrostatic potential difference of one volt.
