Frequently Asked Questions
-
What is attopoise used for?
-
Attopoise is used to measure extremely small dynamic viscosities, especially in molecular-scale studies and nanoscale simulations.
-
Why convert attopoise to pound-force second per square inch?
-
This conversion allows researchers and engineers to express very small viscosity values in US customary units commonly used in industry.
-
Are there challenges when converting between these units?
-
Yes, because attopoise and pound-force second per square inch differ greatly in magnitude, the converted values can be extremely small, which may be hard to use in practical engineering.
Key Terminology
-
Attopoise [aP]
