How to Convert electronvolts to kilojoules
To convert electronvolts to kilojoules, multiply the value by the conversion factor:
For example: 10 eV = 1.6022e-21 kJ
About electronvolts and kilojoules
The Conversion Formula
To convert electronvolts to kilojoules, multiply the value by the conversion factor: 1 eV = 1.6022e-22 kJ. For a worked example, suppose you need to convert 25 eV to kilojoules: 25 × 1.6022e-22 = 4.0054e-21 kJ. To convert in the opposite direction, divide by 1.6022e-22, or equivalently multiply by 6.2415e+21.
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.
About kilojoules
The kilojoule (kJ) is the standard unit for food energy in most of the world (Australia, Europe, etc.), replacing the Calorie. One food Calorie (kcal) is approximately 4.2 kJ. It provides a more precise measure of energy intake than the large Calorie. kilojoules are commonly used in Food labels (Global), Exercise machines, Diet planning, and Thermodynamics, Metabolic rate tracking.
A slice of bread has about 300-400 kJ.
When Would You Convert electronvolts to kilojoules?
Converting between electronvolts and kilojoules 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 eV = 1.6022e-22 kJ) memorized or bookmarked can save time in professional and everyday contexts alike.
