Frequently asked questions
What is the source unit in this conversion?
The source unit is the Erg (erg). An erg is a CGS energy unit.
What is the destination unit in this conversion?
The destination unit is the Millijoule (mJ). Millijoule is 0.001 joule units.
How do I convert Erg to Millijoule?
Multiply the Erg value by 0.0001. For example, 10 erg × 0.0001 = 0.001 mJ.
Is the Erg to Millijoule conversion exact?
Yes. Both units belong to the same engineering measurement family (energy), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Erg needs to be compared with, or reported in, Millijoule, such as in engineering, scientific, or industrial calculations.
Can I convert Millijoule back to Erg?
Yes. Multiply the Millijoule value by 10000 to get Erg.

About this conversion
This page converts Erg (erg) to Millijoule (mJ) within the engineering converter.
An erg is a CGS energy unit. Millijoule is 0.001 joule units.
The formula is mJ = erg × 0.0001, based on each unit's fixed relationship to the energy base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
