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

Formula
BTU (BTU) 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.
BTU relates to its own energy base unit by a factor of 1055.06. at relates to its own pressure and mechanical stress base unit by a factor of 98066.5.

Frequently asked questions
Can BTU be converted to Technical atmosphere?
Not directly. BTU 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 BTU used for?
The BTU (BTU) is a unit of energy. British thermal unit.
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 BTU and Technical atmosphere don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert BTU to instead?
Use another energy unit, such as one of the related BTU 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 BTU (BTU) and Technical atmosphere (at) within the engineering converter.
British thermal unit. Technical atmosphere is kilogram-force per square centimeter.
Because BTU 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.
