How to Convert Electronvolts to Megacalories

To convert a electronvolt measurement to a megacalorie measurement, multiply the energy by the conversion ratio. One electronvolt is equal to 3.8293E-26 megacalories, so use this simple formula to convert:

megacalories = electronvolts × 3.8293E-26

The energy in megacalories is equal to the electronvolts multiplied by 3.8293E-26.

For example, here's how to convert 5 electronvolts to megacalories using the formula above.
5 eV = (5 × 3.8293E-26) = 1.9146E-25 Mcal

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


The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.

Electronvolts can be abbreviated as eV, for example 1 electronvolt can be written as 1 eV.

Energy in electronvolts can be expressed using the following formula: E = qV

The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.


One megacalorie is equal to 1,000,000 calories, which are the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius. One megacalorie is equal to 4.184 megajoules.

Megacalories can be abbreviated as Mcal, for example 1 megacalorie can be written as 1 Mcal.
