The formula to calculate Kiloelectron-volts (keV) from Electron-volts (eV) is:
\[ E (\text{keV}) = \frac{E (\text{eV})}{1000} \]
Where:
Electron-volt (eV) is a unit of energy, representing the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt. Kiloelectron-volt (keV) is a unit of energy, representing 1000 electron-volts. The conversion from electron-volts to kiloelectron-volts is straightforward: divide the energy in electron-volts by 1000[^1^].
Let's assume the following value:
Using the formula:
\[ E = \frac{5000}{1000} \]
\[ E = 5 \text{ keV} \]
The Energy (keV) is 5 keV.
