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

Formula
Atmosphere (atm) measures pressure and mechanical stress, while Kilojoule (kJ) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
atm relates to its own pressure and mechanical stress base unit by a factor of 101325. kJ relates to its own energy base unit by a factor of 1000.

Frequently asked questions
Can Atmosphere be converted to Kilojoule?
Not directly. Atmosphere measures pressure and mechanical stress and Kilojoule 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 Atmosphere used for?
The Atmosphere (atm) is a unit of pressure and mechanical stress. A standard atmosphere is exactly 101,325 pascals.
What is Kilojoule used for?
The Kilojoule (kJ) is a unit of energy. Kilojoule is 1000 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 Atmosphere and Kilojoule don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Atmosphere to instead?
Use another pressure and mechanical stress unit, such as one of the related Atmosphere conversions linked below.
What should I convert Kilojoule to instead?
Use another energy unit, such as one of the related Kilojoule conversions linked below.

About this conversion
This page compares Atmosphere (atm) and Kilojoule (kJ) within the engineering converter.
A standard atmosphere is exactly 101,325 pascals. Kilojoule is 1000 joule units.
Because Atmosphere measures pressure and mechanical stress and Kilojoule 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.
