How to Convert Electronvolts to Kiloelectronvolts

To convert an electronvolt measurement to a kiloelectronvolt measurement, divide the energy by the conversion ratio. One kiloelectronvolt is equal to 1,000 electronvolts, so use this simple formula to convert:

kiloelectronvolts = electronvolts ÷ 1,000

The energy in kiloelectronvolts is equal to the electronvolts divided by 1,000.

For example, here's how to convert 500 electronvolts to kiloelectronvolts using the formula above.
500 eV = (500 ÷ 1,000) = 0.5 keV

Electronvolts and kiloelectronvolts are both units used to measure energy. Keep reading to learn more about each unit of measure.

Electronvolts

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

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