How to Convert Megaelectronvolts to Calories

To convert a megaelectronvolt measurement to a calorie measurement, multiply the energy by the conversion ratio. One megaelectronvolt is equal to 3.8293E-14 calories, so use this simple formula to convert:

calories = megaelectronvolts × 3.8293E-14

The energy in calories is equal to the megaelectronvolts multiplied by 3.8293E-14.

For example, here's how to convert 5 megaelectronvolts to calories using the formula above.
5 MeV = (5 × 3.8293E-14) = 1.9146E-13 cal

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


Megaelectronvolts can be abbreviated as MeV, for example 1 megaelectronvolt can be written as 1 MeV.


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.
