How to Convert Electronvolts to Kiloelectronvolts

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

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.
