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 Megawatt Hour?
A megawatt-hour equals 1,000 kilowatt-hours, or 3.6 gigajoules.
Common contexts: utility-scale power, grid storage.
