Understanding the Units
What is a Joule?
The joule is the SI derived unit of energy, equal to the work done by a force of one newton acting through a distance of one meter (1 J = 1 N·m = 1 W·s).
Named after James Prescott Joule (1818–1889), the English physicist who demonstrated the mechanical equivalent of heat.
Common contexts: physics, chemistry, engineering.
What is a Megaelectronvolt?
A megaelectronvolt equals one million electronvolts (10⁶ eV).
Common contexts: nuclear physics, gamma-ray spectroscopy.
