How to Convert Megacalories to Electronvolts

To convert a measurement in megacalories to a measurement in electronvolts, multiply the energy by the following conversion ratio: 2.6114E+25 electronvolts/megacalorie.

Since one megacalorie is equal to 2.6114E+25 electronvolts, you can use this simple formula to convert:

electronvolts = megacalories × 2.6114E+25

The energy in electronvolts is equal to the energy in megacalories multiplied by 2.6114E+25.

For example, here's how to convert 5 megacalories to electronvolts using the formula above.
electronvolts = (5 Mcal × 2.6114E+25) = 1.3057E+26 eV

How Many Electronvolts Are in a Megacalorie?

There are 2.6114E+25 electronvolts in a megacalorie, which is why we use this value in the formula above.

1 Mcal = 2.6114E+25 eV

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

What Is a Megacalorie?

One megacalorie is equal to 1,000,000 calories, which is 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.

What Is an Electronvolt?

An electronvolt is the amount of energy required to accelerate an electron through a difference in electric potential of one volt in vacuum. One electronvolt is equal to the charge of 1.602176634 × 10−19 C, and is equal to the energy of 1.602176634 × 10−19 Joules.[1]

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.
