What Is This Tool?
This converter facilitates the transformation of pressure values from the technical atmosphere (a legacy unit) into decipascal, an SI derived unit ideal for representing very fine pressure magnitudes accurately.
How to Use This Tool?
-
Enter the pressure value in atmosphere technical [at]
-
Select 'atmosphere technical [at]' as the source unit
-
Choose 'decipascal [dPa]' as the target unit
-
Click convert to see the equivalent pressure in decipascal
-
Use the result for precise pressure analysis or sensor calibration
Key Features
-
Converts pressure values from atmosphere technical [at] to decipascal [dPa]
-
Provides exact conversion using the defined rate 1 at = 980665 dPa
-
Supports interpretation of historical engineering data
-
Useful for calibration and measurements requiring fine pressure resolution
-
Browser-based and easy to use without additional installations
Examples
-
2 atmosphere technical [at] converts to 1,961,330 decipascal [dPa]
-
0.5 atmosphere technical [at] converts to 490,332.5 decipascal [dPa]
Common Use Cases
-
Converting legacy pressure ratings from older technical and engineering documents
-
Calibrating acoustic sensors using small pressure increments
-
Performing laboratory and cleanroom pressure measurements requiring precise control
-
Analyzing vacuum systems and fine gas-flow experiments
-
Interpreting and comparing older kgf/cm² pressure specifications with SI units
Tips & Best Practices
-
Always verify the source unit as atmosphere technical [at] to ensure accurate conversion
-
Use the converted decipascal value for applications demanding high-resolution pressure data
-
Handle large numerical results carefully to avoid computational errors
-
Understand that atmosphere technical is non-SI and consider pascal equivalents for standardization
-
Apply this conversion when working with older equipment or legacy pressure data
Limitations
-
Atmosphere technical is a deprecated, non-SI unit
-
Conversion produces very large decipascal values that may require special numeric handling
-
Direct use of dPa from at may not be suitable for all modern applications
-
Legacy nature of at might limit its relevance in current pressure standards
Frequently Asked Questions
-
What is atmosphere technical (at)?
-
Atmosphere technical is a non-SI pressure unit equal to one kilogram-force per square centimetre, historically used in engineering and industrial contexts.
-
Why convert atmosphere technical to decipascal?
-
Conversion helps translate legacy pressure measurements into finely resolved SI units, facilitating modern applications like sensor calibration and precise laboratory analysis.
-
Is atmosphere technical still a standard unit?
-
No, atmosphere technical is considered deprecated in favor of pascal, the SI pressure unit, for standardization.
Key Terminology
