What Is This Tool?
This converter transforms pressure measurements from atmosphere technical (at), a legacy unit defined as kilogram-force per square centimetre, into kilogram-force per square millimeter (kgf/mm²), a unit often used in materials testing and mechanical engineering.
How to Use This Tool?
-
Enter the pressure value in atmosphere technical [at]
-
Select kilogram-force per square millimeter as the target unit
-
Click the convert button to get the equivalent pressure
-
Review the converted value for your engineering or materials testing needs
Key Features
-
Converts pressure units from atmosphere technical [at] to kilogram-force/sq. millimeter

Tips & Best Practices
-
Double-check units when converting between different pressure scales
-
Use this tool primarily for legacy data or specialized engineering charts
-
Be cautious of scale differences between square centimetres and square millimeters
-
Consider limitations when precise SI unit accuracy is needed
Limitations
-
Both atmosphere technical and kilogram-force/sq. millimeter are non-SI gravitational units
-
Minor inaccuracies may occur when converting to precise SI units
-
Different referenced area sizes may lead to scale confusion
-
Mainly suited for legacy and specialized applications, not general scientific use
Frequently Asked Questions
-
What is atmosphere technical (at)?
-
Atmosphere technical (at) is a legacy pressure unit defined as one kilogram-force per square centimetre, commonly used in older industrial and engineering literature.
-
Why convert atmosphere technical to kilogram-force/sq. millimeter?
-
Converting allows interpreting historical pressure data at a smaller scale unit frequently used in materials testing and mechanical engineering for tensile strength and contact stresses.
-
Are these units part of the International System of Units (SI)?
-
No, both atmosphere technical and kilogram-force per square millimeter are non-SI gravitational units used mainly in legacy and specialized contexts.
Key Terminology
-
Atmosphere Technical [at]
-
A non-SI pressure unit defined as one kilogram-force per square centimetre, used mainly in historical engineering and industrial contexts.
-
Kilogram-force per Square Millimeter (kgf/mm²)
-
A non-SI gravitational unit of pressure equal to one kilogram-force applied over one square millimeter, often used in materials testing and mechanical engineering.
