Convert erg to millijoule
Please provide values below to convert erg [erg] to millijoule [mJ], or Convert millijoule to erg.
1 erg = 0.0001 mJ. To convert erg to millijoule, multiply the value by 0.0001; to go the other way, divide by it (1 mJ = 10000 erg). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 erg = 0.0001 mJ
- 1 mJ = 10000 erg
- 10 erg = 0.001 mJ
- 100 erg = 0.01 mJ
How to Convert Erg to Millijoule
1 erg = 0.0001 mJ
Example: convert 15 erg to mJ:
15 erg = 15 × 0.0001 mJ = 0.0015 mJ

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.
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 erg in millijoule?
1 erg (erg) = 0.0001 millijoule (mJ).
How do you convert erg to millijoule?
Multiply the erg value by 0.0001. For example, 25 erg × 0.0001 = 0.0025 mJ.
What is 10 erg in millijoule?
10 erg = 0.001 mJ.
Which unit is larger, the erg or the millijoule?
The millijoule is the larger unit: 1 erg equals only 0.0001 mJ.
