Convert megajoule to millijoule
Please provide values below to convert megajoule [MJ] to millijoule [mJ], or Convert millijoule to megajoule.
1 MJ = 1000000000 mJ. To convert megajoule to millijoule, multiply the value by 1000000000; to go the other way, divide by it (1 mJ = 1e-09 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 = 1000000000 mJ
- 1 mJ = 1e-09 MJ
- 10 MJ = 10000000000 mJ
- 100 MJ = 100000000000 mJ
How to Convert Megajoule to Millijoule
1 MJ = 1000000000 mJ
Example: convert 15 MJ to mJ:
15 MJ = 15 × 1000000000 mJ = 15000000000 mJ

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.
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.
