How to Convert Kilocalories to Electronvolts

To convert a measurement in kilocalories to a measurement in electronvolts, multiply the energy by the following conversion ratio: 2.6114E+22 electronvolts/kilocalorie.

Since one kilocalorie is equal to 2.6114E+22 electronvolts, you can use this simple formula to convert:

electronvolts = kilocalories × 2.6114E+22

The energy in electronvolts is equal to the energy in kilocalories multiplied by 2.6114E+22.

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

electronvolts = (5 kcal × 2.6114E+22) = 1.3057E+23 eV

How Many Electronvolts Are in a Kilocalorie?

There are 2.6114E+22 electronvolts in a kilocalorie, which is why we use this value in the formula above.

1 kcal = 2.6114E+22 eV

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

What Is a Kilocalorie?

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal; for example, 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.

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.
