To convert a measurement in kiloelectronvolts to a measurement in kilocalories, multiply the energy by the following conversion ratio: 3.8293E-20 kilocalories/kiloelectronvolt.

Since one kiloelectronvolt is equal to 3.8293E-20 kilocalories, you can use this simple formula to convert:

kilocalories = kiloelectronvolts × 3.8293E-20

The energy in kilocalories is equal to the energy in kiloelectronvolts multiplied by 3.8293E-20.

For example, here's how to convert 5.0E+19 kiloelectronvolts to kilocalories using the formula above.
kilocalories = (5.0E+19 keV × 3.8293E-20) = 1.914647 kcal

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

What is a Kiloelectronvolt?

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

What is a Kilocalorie?

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal; for example, 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.
