How to Convert Kiloelectronvolts to Calories

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

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

calories = kiloelectronvolts ÷ 2.6114E+16

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

For example, here's how to convert 5.0E+16 kiloelectronvolts to calories using the formula above.
5.0E+16 keV = (5.0E+16 ÷ 2.6114E+16) = 1.914647 cal

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


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


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.
