Convert megajoule to kilojoule
Please provide values below to convert megajoule [MJ] to kilojoule [kJ], or Convert kilojoule to megajoule.
1 MJ = 1000 kJ. To convert megajoule to kilojoule, multiply the value by 1000; to go the other way, divide by it (1 kJ = 0.001 MJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 MJ = 1000 kJ
- 1 kJ = 0.001 MJ
- 10 MJ = 10000 kJ
- 100 MJ = 100000 kJ
How to Convert Megajoule to Kilojoule
1 MJ = 1000 kJ
Example: convert 15 MJ to kJ:
15 MJ = 15 × 1000 kJ = 15000 kJ

Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
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.
