Megaelectron-volt
MeV
Definition
The Megaelectron-volt is related to the fundamental properties of electrons and represents a fundamental scale in atomic and particle physics. It is derived from the electron's mass, charge, or other fundamental properties and provides a natural unit for atomic-scale phenomena.
History/Origin
The Megaelectron-volt was determined through experiments in atomic and particle physics during the early 20th century. It became a fundamental constant in quantum mechanics and atomic physics, providing a natural scale for atomic and subatomic phenomena.
Current Use
The Megaelectron-volt is used in atomic physics for calculating atomic properties, in quantum mechanics for describing electron behavior, in particle physics as a fundamental constant, and in chemistry for molecular calculations involving electron properties.

Joule
J
Definition
The joule (symbol: J) is the SI base unit of energy, work, and heat. It is defined as the work done when a force of one newton moves an object one meter in the direction of the force. One joule equals one newton-meter or one watt-second.
History/Origin
The joule was named after James Prescott Joule (1818-1889), an English physicist who established the mechanical equivalent of heat. It was officially adopted as the SI unit of energy in 1948, replacing the calorie in scientific contexts.
Current Use
Joules are used universally in physics, engineering, and chemistry for measuring energy, work, and heat. Applications include electrical energy calculations, mechanical work, thermal energy, and energy efficiency measurements in all scientific and industrial fields.
