Understanding the Units

What is a Quad?

A quad equals one quadrillion (10¹⁵) BTU, about 1.055 exajoules — used in national-scale energy statistics.

Common contexts: national energy reporting (US EIA).

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.
