What Is This Tool?
This converter transforms dynamic viscosity measurements from poundal second per square foot, an imperial unit used in older FPS systems, into micropoise [µP], a cgs unit suited for very low viscosity values. It helps translate viscosity data between different unit systems commonly used in engineering, microfluidics, and scientific research.

-
Micropoise unit is specialized for low viscosity ranges and may not suit all applications
Frequently Asked Questions
-
What does poundal second per square foot measure?
-
It measures dynamic (absolute) viscosity as a force of one poundal applied over one second across one square foot, representing fluid resistance to shear flow in imperial units.
-
When should I use micropoise [µP] units?
-
Micropoise is used for very low dynamic viscosities, such as those in gases or microfluidic studies, and is a cgs unit equal to one millionth of a poise.
-
Why convert from poundal second/square foot to micropoise?
-
Conversion enables comparison and compatibility of viscosity data between older imperial systems and modern cgs units, which is essential for engineering, research, and historical data analysis.
