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

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.
Millijoule
A millijoule (mJ) is a unit of energy equal to one thousandth of a joule, where 1 joule equals 1 newton meter or 1 kg·m²/s².
History/Origin
The millijoule is derived from the SI base unit joule, with the prefix 'milli' indicating a factor of 10⁻³. It has been used in scientific and engineering contexts to measure small amounts of energy, especially in fields like electronics and biomechanics.
Current Use
The millijoule is commonly used today to quantify small energy quantities in electronics, biomedical applications, and energy measurements where precision at a small scale is required.
