Convert gigajoule to joule
Please provide values below to convert gigajoule [GJ] to joule [J], or Convert joule to gigajoule.
1 GJ = 1000000000 J. To convert gigajoule to joule, multiply the value by 1000000000; to go the other way, divide by it (1 J = 1e-09 GJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 GJ = 1000000000 J
- 1 J = 1e-09 GJ
- 10 GJ = 10000000000 J
- 100 GJ = 100000000000 J
How to Convert Gigajoule to Joule
1 GJ = 1000000000 J
Example: convert 15 GJ to J:
15 GJ = 15 × 1000000000 J = 15000000000 J

Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
