Convert kilojoule to microjoule
Please provide values below to convert kilojoule [kJ] to microjoule [µJ], or Convert microjoule to kilojoule.
1 kJ = 1000000000 µJ. To convert kilojoule to microjoule, multiply the value by 1000000000; to go the other way, divide by it (1 µJ = 1e-09 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 = 1000000000 µJ
- 1 µJ = 1e-09 kJ
- 10 kJ = 10000000000 µJ
- 100 kJ = 100000000000 µJ
How to Convert Kilojoule to Microjoule
1 kJ = 1000000000 µJ
Example: convert 15 kJ to µJ:
15 kJ = 15 × 1000000000 µJ = 15000000000 µJ

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.
Microjoule
A microjoule (µJ) is a unit of energy equal to one millionth of a joule, used to measure small amounts of energy.
History/Origin
The microjoule was introduced as part of the metric system to facilitate the measurement of very small energy quantities, especially in scientific and engineering contexts, with the adoption of the International System of Units (SI).
Current Use
Microjoules are commonly used in fields such as electronics, physics, and biology to quantify small energy transfers, signals, or reactions, often in research and technical applications.
