Tips & Best Practices
-
Ensure input values are accurate to maintain precision in conversion
-
Use this tool for translating nanoscale viscosity values into imperial units
-
Compare viscosity readings between SI and imperial systems carefully
-
Be cautious with rounding due to the very small scale of attopoise values

Small magnitude of attopoise requires careful attention to precision and significant figures
-
Poundal second per square foot is rarely used in modern scientific work
-
Comparisons across unit systems may need additional validation for consistency
Frequently Asked Questions
-
What is an attopoise?
-
An attopoise (aP) is a unit of dynamic viscosity equal to 10^-18 poise or 1×10^-19 pascal-seconds, used for describing extremely small viscosities in molecular and nanoscale contexts.
-
Why convert attopoise to poundal second per square foot?
-
Conversion is useful for translating nanoscale viscosity values into the imperial system, facilitating engineering calculations and comparisons with historical FPS-based data.
-
Is poundal second per square foot commonly used today?
-
It is rarely used in modern scientific research but remains relevant in certain engineering fields and when handling older experimental results.
Key Terminology
-
Attopoise (aP)
-
A unit of dynamic viscosity equal to 10^-18 poise or 1×10^-19 pascal-second, used for very small viscosities at molecular and nanoscale levels.
