How to Convert Calories to Electronvolts

To convert a calorie measurement to a electronvolt measurement, multiply the energy by the conversion ratio. One calorie is equal to 2.6114E+19 electronvolts, so use this simple formula to convert:

electronvolts = calories × 2.6114E+19

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

For example, here's how to convert 5 calories to electronvolts using the formula above.
5 cal = (5 × 2.6114E+19) = 1.3057E+20 eV

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

Calories

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.

Electronvolts

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.
