About calories and electronvolts
The Conversion Formula
To convert calories to electronvolts, multiply the value by the conversion factor: 1 cal = 2.6114e+19 eV. For a worked example, suppose you need to convert 25 cal to electronvolts: 25 × 2.6114e+19 = 6.5286e+20 eV. To convert in the opposite direction, divide by 2.6114e+19, or equivalently multiply by 3.8293e-20.
About calories
The calorie (lowercase c) was originally defined as the heat required to raise 1 gram of water by 1°C. It is a tiny unit, often called the 'gram calorie'. It is mostly used in chemistry and physics today, not for food. calories are commonly used in Chemistry experiments, Thermodynamics, Specific heat capacity, and Physics problems.
Heating 1 gram of water by 1°C takes 1 calorie.
About electronvolts
The electronvolt (eV) is the tiny unit of energy used in particle physics. It is the energy gained by an electron accelerating through 1 volt. It is essential for describing photon energy, chemical bonds, and nuclear reactions. electronvolts are commonly used in Particle physics, Semiconductors, Nuclear energy, and Chemistry bonds, Microscopy.
A photon of visible light has an energy of about 2-3 eV.
When Would You Convert calories to electronvolts?
Converting between calories and electronvolts is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 cal = 2.6114e+19 eV) memorized or bookmarked can save time in professional and everyday contexts alike.
