Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Erg and Rontonewton measure different quantities, so no single result applies.

Formula
Erg (erg) measures energy, while Rontonewton (rN) measures force. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
erg relates to its own energy base unit by a factor of 1e-07. rN relates to its own force base unit by a factor of 0.
Conversion table
| Erg (erg) | 1e-07 × energy base unit |

Frequently asked questions
Can Erg be converted to Rontonewton?
Not directly. Erg measures energy and Rontonewton measures force. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Erg used for?
The Erg (erg) is a unit of energy. An erg is a CGS energy unit.
What is Rontonewton used for?
The Rontonewton (rN) is a unit of force. Rontonewton is 1e-27 newton units.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Erg and Rontonewton don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Erg to instead?
Use another energy unit, such as one of the related Erg conversions linked below.
What should I convert Rontonewton to instead?
Use another force unit, such as one of the related Rontonewton conversions linked below.

About this conversion
This page compares Erg (erg) and Rontonewton (rN) within the engineering converter.
An erg is a CGS energy unit. Rontonewton is 1e-27 newton units.
Because Erg measures energy and Rontonewton measures force, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
