Convert microjoule to millijoule
Please provide values below to convert microjoule [µJ] to millijoule [mJ], or Convert millijoule to microjoule.
1 µJ = 0.001 mJ. To convert microjoule to millijoule, multiply the value by 0.001; to go the other way, divide by it (1 mJ = 1000 µJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µJ = 0.001 mJ
- 1 mJ = 1000 µJ
- 10 µJ = 0.01 mJ
- 100 µJ = 0.1 mJ
How to Convert Microjoule to Millijoule
1 µJ = 0.001 mJ
Example: convert 15 µJ to mJ:
15 µJ = 15 × 0.001 mJ = 0.015 mJ

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.
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.
Frequently Asked Questions
What is 1 microjoule in millijoule?
1 microjoule (µJ) = 0.001 millijoule (mJ).
How do you convert microjoule to millijoule?
Multiply the microjoule value by 0.001. For example, 25 µJ × 0.001 = 0.025 mJ.
What is 10 microjoule in millijoule?
10 µJ = 0.01 mJ.
Which unit is larger, the microjoule or the millijoule?
The millijoule is the larger unit: 1 µJ equals only 0.001 mJ.
