#### eV to keV

The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as eV; for example, 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.

Kiloelectronvolts can be abbreviated as keV; for example, 1 kiloelectronvolt can be written as 1 keV.

#### How to convert eV to keV

One electron-volt is equal to thousandth of a kiloelectron-volt:

1eV = 0.001keV

The energy in kiloelectron-volt E_{(keV)} is equal to the energy in electron-volt E_{(eV)} divided by 1000:

E_{(keV)} = E_{(eV)} / 1000

#### Example

Convert 500eV to keV:

E_{(keV)} = 500eV / 1000 = 0.5keV
