How to Convert Calories to Kiloelectronvolts

To convert a calorie measurement to a kiloelectronvolt measurement, multiply the energy by the conversion ratio.

Since one calorie is equal to 2.6114E+16 kiloelectronvolts, you can use this simple formula to convert:

kiloelectronvolts = calories × 2.6114E+16

The energy in kiloelectronvolts is equal to the calories multiplied by 2.6114E+16.

For example, here's how to convert 5 calories to kiloelectronvolts using the formula above.
5 cal = (5 × 2.6114E+16) = 1.3057E+17 keV

How Many Kiloelectronvolts are in a Calorie?

There are 2.6114E+16 kiloelectronvolts in a calorie, which is why we use this value in the formula above.

1 cal = 2.6114E+16 keV

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


One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.

When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."

Calories can be abbreviated as cal; for example, 1 calorie can be written as 1 cal.


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