## How to Convert Electronvolts to Calories

To convert an electronvolt measurement to a calorie measurement, multiply the energy by the conversion ratio.

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

The energy in calories is equal to the electronvolts multiplied by 3.8293E-20.

**For example,**here's how to convert 5.0E+19 electronvolts to calories using the formula above.

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

## 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.

## 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.
