Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Gigajoule and Technical atmosphere measure different quantities, so no single result applies.
Reserved above the conversion cards and below the converter.
Formula
Gigajoule (GJ) measures energy, while Technical atmosphere (at) measures pressure and mechanical stress. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
GJ relates to its own energy base unit by a factor of 1000000000. at relates to its own pressure and mechanical stress base unit by a factor of 98066.5.
Conversion table
| Gigajoule (GJ) | 1000000000 × energy base unit |
| Technical atmosphere (at) | 98066.5 × pressure and mechanical stress base unit |

Frequently asked questions
Can Gigajoule be converted to Technical atmosphere?
Not directly. Gigajoule measures energy and Technical atmosphere 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 Gigajoule used for?
The Gigajoule (GJ) is a unit of energy. Gigajoule is 1000000000 joule units.
What is Technical atmosphere used for?
The Technical atmosphere (at) is a unit of pressure and mechanical stress. Technical atmosphere is kilogram-force per square centimeter.
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 Gigajoule and Technical atmosphere don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Gigajoule to instead?
Use another energy unit, such as one of the related Gigajoule conversions linked below.
What should I convert Technical atmosphere to instead?
Use another pressure and mechanical stress unit, such as one of the related Technical atmosphere conversions linked below.

About this conversion
This page compares Gigajoule (GJ) and Technical atmosphere (at) within the engineering converter.
Gigajoule is 1000000000 joule units. Technical atmosphere is kilogram-force per square centimeter.
Because Gigajoule measures energy and Technical atmosphere 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.
