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

Formula
Erg (erg) measures energy, while mmHg (mmHg) measures pressure and mechanical stress. 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. mmHg relates to its own pressure and mechanical stress base unit by a factor of 133.322.
Conversion table
| Erg (erg) | 1e-07 × energy base unit |
| mmHg (mmHg) | 133.322 × pressure and mechanical stress base unit |

Frequently asked questions
Can Erg be converted to mmHg?
Not directly. Erg measures energy and mmHg measures pressure and mechanical stress. 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 mmHg used for?
The mmHg (mmHg) is a unit of pressure and mechanical stress. Millimeters of mercury at standard gravity.
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 mmHg 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 mmHg to instead?
Use another pressure and mechanical stress unit, such as one of the related mmHg conversions linked below.

About this conversion
This page compares Erg (erg) and mmHg (mmHg) within the engineering converter.
An erg is a CGS energy unit. Millimeters of mercury at standard gravity.
Because Erg measures energy and mmHg measures pressure and mechanical stress, 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.
