Tips & Best Practices
-
Double-check unit selections to ensure accurate conversions
-
Use the tool to understand legacy pressure values in modern contexts
-
Be aware of the difference between technical atmosphere and standard atmosphere units
-
Refer to pascals for SI-based precise pressure calculations when possible
Limitations
-
Technical atmosphere is a non-SI unit and differs slightly from the standard atmosphere
-
Poundal/square foot is mainly used in legacy or educational contexts rather than modern engineering
-
Small discrepancies may occur due to differences in force and area definitions across unit systems
Frequently Asked Questions
-
What does one poundal/square foot represent?
-
It is a pressure unit defined as one poundal of force applied over one square foot of area, part of the foot–pound–second system.
-
How is technical atmosphere defined?
-
Technical atmosphere (at) is a non-SI pressure unit defined as one kilogram-force per square centimetre, equal to 98,066.5 pascals.
-
Why convert poundal/square foot to technical atmosphere?
-
This conversion helps interpret legacy FPS pressure data in terms aligned with older industrial and engineering standards.
-
Is technical atmosphere the same as the standard atmosphere?
-
No, the technical atmosphere differs slightly from the standard atmosphere and should be considered separately in precise calculations.
Key Terminology
-
Poundal per square foot
-
A pressure unit from the FPS system, representing one poundal of force applied over a square foot of area.
-
Technical atmosphere (at)
-
A non-SI unit of pressure equal to one kilogram-force per square centimetre, used historically in industrial settings.
-
Foot–pound–second system
-
A system of units based on feet, pounds, and seconds used primarily in some legacy engineering contexts.
-
Kilogram-force per square centimetre
-
A unit of pressure defining the technical atmosphere, relating force to area in metric units.
