## How to Convert Calories to Electronvolts

To convert a measurement in calories to a measurement in electronvolts, multiply the energy by the following conversion ratio: 2.6114E+19 electronvolts/calorie.

Since one calorie is equal to 2.6114E+19 electronvolts, you can use this simple formula to convert:

electronvolts = calories × 2.6114E+19

The energy in electronvolts is equal to the energy in calories multiplied by 2.6114E+19.

**For example,**here's how to convert 5 calories to electronvolts using the formula above.

### How Many Electronvolts Are in a Calorie?

There are **2.6114E+19** electronvolts in a calorie, which is why we use this value in the formula above.

1 cal = 2.6114E+19 eV

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

## What Is a Calorie?

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.

## 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.
