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 Rontojoule (rJ). Rontojoule is 1e-27 joule units.
How do I convert Erg to Rontojoule?
Multiply the Erg value by 1e+20. For example, 10 erg × 1e+20 = 1e+21 rJ.
Is the Erg to Rontojoule 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, Rontojoule, such as in engineering, scientific, or industrial calculations.
Can I convert Rontojoule back to Erg?
Yes. Multiply the Rontojoule value by 0 to get Erg.

About this conversion
This page converts Erg (erg) to Rontojoule (rJ) within the engineering converter.
An erg is a CGS energy unit. Rontojoule is 1e-27 joule units.
The formula is rJ = erg × 1e+20, 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.
