Convert millijoule to erg
Please provide values below to convert millijoule [mJ] to erg [erg], or Convert erg to millijoule.
1 mJ = 10000 erg. To convert millijoule to erg, multiply the value by 10000; to go the other way, divide by it (1 erg = 0.0001 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 = 10000 erg
- 1 erg = 0.0001 mJ
- 10 mJ = 100000 erg
- 100 mJ = 1000000 erg
How to Convert Millijoule to Erg
1 mJ = 10000 erg
Example: convert 15 mJ to erg:
15 mJ = 15 × 10000 erg = 150000 erg

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.
Erg
The erg is a unit of energy in the centimeter-gram-second (CGS) system, defined as the amount of work done when a force of one dyne displaces an object by one centimeter.
History/Origin
The erg was introduced in the late 19th century as part of the CGS system of units, primarily used in physics to measure small amounts of energy before the adoption of the SI system.
Current Use
Today, the erg is largely obsolete and rarely used outside of specific scientific contexts, with the SI unit joule being the standard for energy measurement. It remains relevant in some fields like astrophysics and theoretical physics.
