How to Convert Joules to Kiloelectronvolts

To convert a measurement in joules to a measurement in kiloelectronvolts, multiply the energy by the following conversion ratio: 6.2415E+15 kiloelectronvolts/joule.

Since one joule is equal to 6.2415E+15 kiloelectronvolts, you can use this simple formula to convert:

kiloelectronvolts = joules × 6.2415E+15

The energy in kiloelectronvolts is equal to the energy in joules multiplied by 6.2415E+15.

For example, here's how to convert 5 joules to kiloelectronvolts using the formula above.
kiloelectronvolts = (5 J × 6.2415E+15) = 3.1208E+16 keV

How Many Kiloelectronvolts Are in a Joule?

There are 6.2415E+15 kiloelectronvolts in a joule, which is why we use this value in the formula above.

1 J = 6.2415E+15 keV

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

What Is a Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.[1] One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as J; for example, 1 joule can be written as 1 J.

What Is a Kiloelectronvolt?

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