To convert a measurement in electronvolts to a measurement in kiloelectronvolts, divide the energy by the following conversion ratio: 1,000 electronvolts/kiloelectronvolt.

Since one kiloelectronvolt is equal to 1,000 electronvolts, you can use this simple formula to convert:

kiloelectronvolts = electronvolts ÷ 1,000

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

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

What Is an Electronvolt?

An electronvolt is the amount of energy required to accelerate an electron through a difference in electric potential of one volt in vacuum. One electronvolt is equal to the charge of 1.602176634 × 10−19 C, and is equal to the energy of 1.602176634 × 10−19 Joules.[1]

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.

What Is a Kiloelectronvolt?

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