How to Convert Electronvolts to Kilocalories

To convert an electronvolt measurement to a kilocalorie measurement, multiply the energy by the conversion ratio. One electronvolt is equal to 3.8293E-23 kilocalories, so use this simple formula to convert:

kilocalories = electronvolts × 3.8293E-23

The energy in kilocalories is equal to the electronvolts multiplied by 3.8293E-23.

For example, here's how to convert 5.0E+22 electronvolts to kilocalories using the formula above.
5.0E+22 eV = (5.0E+22 × 3.8293E-23) = 1.914647 kcal

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

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.

Kilocalories

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.
