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 Kiloelectronvolt?
A kiloelectronvolt equals 1,000 electronvolts (10³ eV).
Common contexts: X-ray energy, nuclear medicine.
