Frequently Asked Questions
-
What is pascal second [Pa*s] used for?
-
The pascal second is an SI derived unit for dynamic viscosity, measuring a fluid’s resistance to shear flow, commonly used in mechanical and fluid engineering.
-
Why convert from pascal second to poundal second per square foot?
-
Conversion is essential when working between SI and imperial systems, especially for engineering, fluid-dynamics analyses, and interpreting historical data in FPS units.
-
What should I be careful about when converting units?
-
Ensure unit system consistency and be mindful that poundal second per square foot is less common, which may affect precision and compatibility.
Key Terminology

Pascal second [Pa*s]
-
The SI derived unit of dynamic viscosity, representing one pascal of shear stress per unit shear rate.
-
Poundal second per square foot
-
An imperial unit of dynamic viscosity defined as force of one poundal applied over one second across one square foot area.
-
Dynamic viscosity
-
A measure of a fluid's internal resistance to shear flow.
