Convert kilojoule to gigajoule
Please provide values below to convert kilojoule [kJ] to gigajoule [GJ], or Convert gigajoule to kilojoule.
1 kJ = 1e-06 GJ. To convert kilojoule to gigajoule, multiply the value by 1e-06; to go the other way, divide by it (1 GJ = 1000000 kJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kJ = 1e-06 GJ
- 1 GJ = 1000000 kJ
- 10 kJ = 1e-05 GJ
- 100 kJ = 0.0001 GJ
How to Convert Kilojoule to Gigajoule
1 kJ = 1e-06 GJ
Example: convert 15 kJ to GJ:
15 kJ = 15 × 1e-06 GJ = 1.5e-05 GJ

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.
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.
Frequently Asked Questions
What is 1 kilojoule in gigajoule?
1 kilojoule (kJ) = 1e-06 gigajoule (GJ).
How do you convert kilojoule to gigajoule?
Multiply the kilojoule value by 1e-06. For example, 25 kJ × 1e-06 = 2.5e-05 GJ.
What is 10 kilojoule in gigajoule?
10 kJ = 1e-05 GJ.
Which unit is larger, the kilojoule or the gigajoule?
The gigajoule is the larger unit: 1 kJ equals only 1e-06 GJ.
