Convert gigajoule to kilojoule
Please provide values below to convert gigajoule [GJ] to kilojoule [kJ], or Convert kilojoule to gigajoule.
1 GJ = 1000000 kJ. To convert gigajoule to kilojoule, multiply the value by 1000000; to go the other way, divide by it (1 kJ = 1e-06 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 = 1000000 kJ
- 1 kJ = 1e-06 GJ
- 10 GJ = 10000000 kJ
- 100 GJ = 100000000 kJ
How to Convert Gigajoule to Kilojoule
1 GJ = 1000000 kJ
Example: convert 15 GJ to kJ:
15 GJ = 15 × 1000000 kJ = 15000000 kJ

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.
Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
