What Is This Tool?
This unit converter allows you to change pressure measurements from kilogram-force per square millimeter (kgf/mm²) to atmosphere technical (at). Both units represent pressure values commonly found in older engineering texts and technical datasets. The tool is designed to assist engineers and technicians in translating legacy pressure data into a more understandable form.
How to Use This Tool?
-
Enter the pressure value measured in kilogram-force per square millimeter
-
Select the target unit as atmosphere technical [at]
-
Click the convert button to see the equivalent pressure in atmosphere technical
-
Use the result to compare or interpret legacy pressure specifications effectively
Key Features
-
Converts between kilogram-force/sq. millimeter and atmosphere technical [at]
-
Supports legacy pressure unit conversions used in materials testing and industrial equipment
-
Browser-based and easy to use without any installations
-
Provides quick and clear results for interpreting older engineering documents
Examples
-
2 Kilogram-force/sq. millimeter converts to 200 Atmosphere technical [at]
-
0.5 Kilogram-force/sq. millimeter equals 50 Atmosphere technical [at]
Common Use Cases
-
Reporting tensile or yield strength of metals and alloys in older materials testing charts
-
Specifying stresses in mechanical parts like fasteners and bearings from legacy data
-
Interpreting technical literature where non-SI gravitational pressure units are used
-
Converting older industrial pressure values to compare with modern SI units
-
Maintaining historical industrial equipment that uses pressure ratings in technical atmospheres
Tips & Best Practices
-
Always verify the units used in your source documents to ensure correct conversion
-
Use this converter primarily for interpreting older or historical data rather than precise modern standards
-
Remember that the atmosphere technical unit differs slightly from the standard atmosphere
-
Cross-check results when accurate engineering calculations require SI units like pascals
-
Be aware that both units are gravitational and rely on standard gravity assumptions
Limitations
-
Both units are non-SI and based on gravitational force, subject to standard gravity conditions
-
Atmosphere technical differs slightly from the standard atmosphere, affecting precise comparisons
-
Primarily relevant for legacy documentation rather than current industry standards
-
Conversions assume conventional unit definitions; variations in standard gravity can affect accuracy
Frequently Asked Questions
-
What is the kilogram-force per square millimeter unit used for?
-
It is a non-SI pressure unit used for reporting tensile or yield strength in metals and alloys, specifying contact stresses in mechanical components, and appearing in older technical literature.
-
How does the atmosphere technical [at] differ from the standard atmosphere?
-
The atmosphere technical is a non-SI pressure unit defined as one kilogram-force per square centimetre and is approximately 0.96784 times the standard atmosphere.
-
Why do we need to convert between these two units?
-
Conversion helps interpret and compare legacy pressure data from older engineering documents that use differing non-SI gravitational pressure units.
Key Terminology
-
Kilogram-force per square millimeter
-
A non-SI gravitational pressure unit equal to one kilogram-force applied to an area of one square millimeter.
-
Atmosphere technical [at]
-
A non-SI pressure unit defined as one kilogram-force per square centimetre, commonly used in older industrial and engineering contexts.
-
Non-SI unit
-
A measurement unit not part of the International System of Units, often based on traditional or gravitational measures.
