What Is This Tool?
This tool converts pressure values from pound-force per square inch (psi), an imperial pressure unit, to atmosphere technical (at), a non-SI metric pressure unit used historically in engineering. It helps translate legacy pressure data for clearer interpretation.
How to Use This Tool?
-
Enter the pressure value in pound-force per square inch (psi) in the input field
-
Select the unit to convert from (pound-force/square inch) and the unit to convert to (atmosphere technical [at])
-
Click the convert button to get the result instantly
-
Review the converted value shown in atmosphere technical units
-
Use the example conversions provided for guidance if needed
Key Features
-
Converts psi to technical atmospheres accurately using the defined conversion rate
-
Supports pressure units commonly used in engineering and industrial contexts
-
Ideal for interpreting legacy pressure measurements from older technical equipment and literature
-
Easy to use, browser-based interface for quick conversion
-
Provides clear example conversions for user reference
Examples
-
Convert 50 psi: 50 × 0.070306958 = 3.51535 at
-
Convert 100 psi: 100 × 0.070306958 = 7.03070 at
Common Use Cases
-
Interpreting automotive tire and hydraulic system pressure specifications
-
Translating legacy industrial pressure data recorded in technical atmospheres
-
Comparing older engineering documentation pressure values to modern units
-
Supporting maintenance and calibration of legacy pneumatic and hydraulic equipment
Tips & Best Practices
-
Ensure units are correctly selected before converting
-
Use example calculations to verify understanding of conversions
-
Refer to this tool when working with older technical drawings or standards
-
Remember that technical atmospheres differ slightly from standard atmospheres
-
Verify critical measurements using SI units when precision is required
Limitations
-
Technical atmosphere is a non-SI unit and not commonly used in current scientific fields
-
Conversion results should be carefully interpreted due to slight differences (~3%) from standard atmospheres
-
Not suitable for applications requiring strict adherence to modern SI units
-
Does not provide conversion for units outside pound-force per square inch and technical atmospheres
Frequently Asked Questions
-
What is pound-force per square inch (psi)?
-
Pound-force per square inch is an imperial pressure unit representing one pound-force applied to an area of one square inch, commonly used in automotive and hydraulic systems.
-
What does atmosphere technical [at] mean?
-
The technical atmosphere is a non-SI pressure unit defined as one kilogram-force per square centimetre, historically used in engineering and industrial contexts.
-
Why convert psi to atmosphere technical?
-
Converting psi to atmosphere technical is important for interpreting legacy pressure measurements and engineering specifications recorded in older units.
Key Terminology
-
Pound-force per square inch (psi)
-
An imperial pressure unit representing one pound-force applied on one square inch of area.
-
Atmosphere technical (at)
-
A non-SI pressure unit equal to one kilogram-force per square centimetre, used historically in technical contexts.
-
Conversion rate
-
The multiplier used to convert pound-force/square inch values to atmosphere technical units, specifically 1 psi = 0.070306958 at.
