Calorie To Electron Volt (Cal To Ev) Converter

The Calorie to Electron Volt (Cal to eV) Converter is a handy tool designed to help you easily convert energy measurements from calories, a common unit in nutrition and chemistry, to electron volts, a unit frequently used in physics and atomic science. Understanding these units can help you compare energy scales across different scientific fields.

A calorie (Cal) is a unit of energy commonly used to measure the energy content of food. One dietary Calorie (Cal) is equal to 1,000 small calories (cal), and it is defined as the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. In terms of basic units, 1 Calorie equals approximately 4.184 kilojoules (kJ).

An electron volt (eV) is a unit of energy used mainly in atomic and particle physics. It represents the amount of kinetic energy gained or lost by an electron when it moves through an electric potential difference of one volt. One electron volt is equal to approximately 1.602 x 10^-19 joules (J).

The conversion formula between calories and electron volts is based on their equivalent energy in joules. Since 1 Calorie equals about 4.184 x 10³ joules, and 1 eV equals 1.602 x 10^-19 joules, the conversion from calories to electron volts is performed by dividing the energy in joules by the energy of one eV. The formula is:

Energy (eV) = Energy (Cal) × 4.184 × 10³ / 1.602 × 10^-19

This tool simplifies the calculation process, allowing you to input a value in calories and instantly see the equivalent energy in electron volts, making it easier to understand and compare energy scales across different scientific disciplines.
