About electronvolts and joules
The Conversion Formula
To convert electronvolts to joules, multiply the value by the conversion factor: 1 eV = 1.6022e-19 J. For a worked example, suppose you need to convert 25 eV to joules: 25 × 1.6022e-19 = 4.0054e-18 J. To convert in the opposite direction, divide by 1.6022e-19, or equivalently multiply by 6.2415e+18.
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 joules
The Joule (J) is the standard unit of energy in the International System of Units (SI). It is named after James Prescott Joule, who proved that heat is a form of energy. One Joule is the work done by a force of one Newton moving an object one meter. It is a small unit: lifting a small apple one meter takes about 1 Joule. joules are commonly used in Scientific research, Physics education, Electronics ratings, and Kinetic energy calculations, Work done.
The energy of a heartbeat is roughly 1 Joule.
When Would You Convert electronvolts to joules?
Converting between electronvolts and joules 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-19 J) memorized or bookmarked can save time in professional and everyday contexts alike.
