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 Gigajoule?

A gigajoule equals one billion joules (10⁹ J).

Common contexts: natural gas billing, large-scale energy reporting.
