What Is This Tool?
This tool allows users to convert pressure measurements from the technical atmosphere unit, a historical non-SI pressure measure, to the SI unit pascal. It helps interpret and translate older pressure values into modern, standardized units.
How to Use This Tool?
-
Enter the pressure value in atmosphere technical [at]
-
Select the unit to convert to: pascal [Pa]
-
Click the convert button to obtain the pressure in pascals
-
Review the output to apply in engineering or scientific contexts
Key Features
-
Converts technical atmosphere (at) values to pascal (Pa) effortlessly
-
Browser-based and easy to use with intuitive input fields
-
Supports interpretation of legacy engineering and industrial pressure data
-
Provides precise unit definitions and usage contexts
-
Ideal for historical and modern pressure data translation
Examples
-
2 atmosphere technical [at] equals 196133 pascal [Pa]
-
0.5 atmosphere technical [at] equals 49033.25 pascal [Pa]
Common Use Cases
-
Translating legacy boiler or hydraulic pressure ratings to SI units
-
Converting historical pneumatic system pressures for modern analysis
-
Comparing older industrial measurements with current standards
-
Using pascal units in meteorology, physics, and material stress testing
Tips & Best Practices
-
Always verify unit definitions for legacy equipment to ensure correct interpretation
-
Use this tool to align older pressure values with international SI standards
-
Be cautious when comparing technical atmosphere with standard atmosphere or bar units
-
Consult equipment documentation to understand original measurement tolerances
Limitations
-
The technical atmosphere is a non-SI unit and not exactly equal to the standard atmosphere
-
Rounding errors may occur when converting very high or low pressures
-
Inconsistent tolerances in legacy equipment may affect pressure accuracy before conversion
Frequently Asked Questions
-
What is the technical atmosphere unit?
-
The technical atmosphere (at) is a non-SI pressure unit defined as one kilogram-force per square centimetre, equivalent to 98,066.5 pascals.
-
Why convert atmosphere technical to pascal?
-
Conversion helps translate older, legacy pressure measurements into the SI unit system for modern engineering, scientific analysis, and compliance.
-
Is atmosphere technical the same as standard atmosphere?
-
No, atmosphere technical is approximately 0.96784 times the standard atmosphere and should not be directly equated.
