What Is This Tool?
This tool converts pressure measurements from pound-force per square foot, a US customary engineering unit, to atmosphere technical [at], a legacy pressure unit used historically in industrial and engineering fields. It helps translate modern structural and wind load values into older units.

Common Use Cases
-
Specifying building loads such as floor live and roof snow loads in US customary units
-
Assessing wind pressure on walls and roofs for design and code compliance
-
Converting distributed loads on beams and slabs measured in pound-force/square foot
-
Interpreting historical pressure ratings in boilers, hydraulics, and pneumatic systems
-
Comparing legacy technical atmosphere values to modern SI pressure units
Tips & Best Practices
-
Double-check unit selections before converting
-
Use this tool for general conversions and comparative purposes, not precise scientific calculations
-
Be aware of the difference between the technical atmosphere and the standard atmosphere units
-
Refer to legacy documentation to understand context for pressure values expressed in atmosphere technical
-
Consider the approximation inherent in converting between legacy and modern units
Limitations
-
The technical atmosphere is a non-SI unit and not widely used in contemporary measurements
-
Conversion results may vary slightly due to legacy unit approximations
-
This tool does not provide exact scientific precision for critical applications
-
Users must account for differences between technical and standard atmosphere units when necessary
-
May cause confusion if modern standards require only SI units
Frequently Asked Questions
-
What is pound-force per square foot used for?
-
It is used mainly in US customary engineering to specify structural loads, wind pressures on buildings, and distributed loads on structural elements like beams and slabs.
-
What does atmosphere technical [at] represent?
-
The technical atmosphere is a legacy pressure unit defined as one kilogram-force per square centimetre and used mainly in older industrial and engineering contexts.
-
Is atmosphere technical the same as standard atmosphere?
-
No, the technical atmosphere is approximately 0.96784 times a standard atmosphere, so they differ and should not be used interchangeably without consideration.
Key Terminology
-
Pound-force per square foot
-
A US customary unit of pressure representing one pound-force distributed over an area of one square foot, used in structural engineering.
-
Atmosphere technical [at]
-
A legacy non-SI unit of pressure defined as one kilogram-force per square centimetre, commonly found in historical industrial and engineering literature.
-
Pressure
-
The force applied perpendicular to the surface of an object per unit area.
