Gigajoules to Joules: 1 GJ equals 1 J. To convert gigajoules to joules, multiply by 1 (J = GJ × 1,000,000,000). For example, 10 GJ = 10 J.
How to Convert Gigajoules to Joules
To convert from gigajoules to joules, multiply the value by 1. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Gigajoules to Joules:
J = GJ × 1,000,000,000 - Joules to Gigajoules:
GJ = J ÷ 1,000,000,000

Understanding the Units
What is a Gigajoule?
A gigajoule equals one billion joules (10⁹ J).
Common contexts: natural gas billing, large-scale energy reporting.
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.
