feV(femtoelectron volt) – Energy – All In One Units Converts

Unit	feV
Name	femtoelectron volt
Category	Energy
Details	A femtoelectron volt (feV) is a unit of energy used to measure very small energy differences or interactions at a subatomic scale, specifically in the field of particle physics and quantum mechanics. It is derived from the electron volt (eV), which is the energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt. The prefix "femto-" (symbolized by the letter 'f') represents a factor of 10^-15. Therefore, one femtoelectron volt (1 feV) is equal to 10^-15 electron volts (eV). In the international system of units (SI), 1 eV is approximately 1.6 x 10^-19 joules. Hence, 1 feV is approximately 1.6 x 10^-34 joules. This extremely small unit of energy is useful for dealing with particle energy scales and interactions that happen at the quantum level, such as those involving neutrinos or other elementary particles.
