Frequently asked questions
What is the source unit in this conversion?
The source unit is the Joule (J). The joule is the SI derived unit of energy.
What is the destination unit in this conversion?
The destination unit is the Erg (erg). An erg is a CGS energy unit.
How do I convert Joule to Erg?
Multiply the Joule value by 10000000. For example, 10 J × 10000000 = 100000000 erg.
Is the Joule to Erg 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 Joule needs to be compared with, or reported in, Erg, such as in engineering, scientific, or industrial calculations.
Can I convert Erg back to Joule?
Yes. Multiply the Erg value by 1e-07 to get Joule.

About this conversion
This page converts Joule (J) to Erg (erg) within the engineering converter.
The joule is the SI derived unit of energy. An erg is a CGS energy unit.
The formula is erg = J × 10000000, 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.
