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

Formula
Bar (bar) measures pressure and mechanical stress, while Zeptojoule (zJ) 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. zJ relates to its own energy base unit by a factor of 0.
Conversion table
| Bar (bar) | 100000 × pressure and mechanical stress base unit |

Frequently asked questions
Can Bar be converted to Zeptojoule?
Not directly. Bar measures pressure and mechanical stress and Zeptojoule 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 Zeptojoule used for?
The Zeptojoule (zJ) is a unit of energy. Zeptojoule is 1e-21 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 Zeptojoule 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 Zeptojoule to instead?
Use another energy unit, such as one of the related Zeptojoule conversions linked below.

About this conversion
This page compares Bar (bar) and Zeptojoule (zJ) within the engineering converter.
A bar is exactly 100,000 pascals. Zeptojoule is 1e-21 joule units.
Because Bar measures pressure and mechanical stress and Zeptojoule 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.
