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

Formula
Bar (bar) measures pressure and mechanical stress, while Gigajoule (GJ) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
bar relates to its own pressure and mechanical stress base unit by a factor of 100000. GJ relates to its own energy base unit by a factor of 1000000000.
Conversion table
| Bar (bar) | 100000 × pressure and mechanical stress base unit |
| Gigajoule (GJ) | 1000000000 × energy base unit |

Frequently asked questions
Can Bar be converted to Gigajoule?
Not directly. Bar measures pressure and mechanical stress and Gigajoule measures energy. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Bar used for?
The Bar (bar) is a unit of pressure and mechanical stress. A bar is exactly 100,000 pascals.
What is Gigajoule used for?
The Gigajoule (GJ) is a unit of energy. Gigajoule is 1000000000 joule 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 Bar and Gigajoule don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Bar to instead?
Use another pressure and mechanical stress unit, such as one of the related Bar conversions linked below.
What should I convert Gigajoule to instead?
Use another energy unit, such as one of the related Gigajoule conversions linked below.

About this conversion
This page compares Bar (bar) and Gigajoule (GJ) within the engineering converter.
A bar is exactly 100,000 pascals. Gigajoule is 1000000000 joule units.
Because Bar measures pressure and mechanical stress and Gigajoule measures energy, 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.
