Frequently Asked Questions
-
What does pound-force second per square foot measure?
-
It is a dynamic viscosity unit in the Imperial/US customary system that quantifies a fluid’s resistance to shear flow.
-
Why convert from pound-force second/sq. foot to kilogram-force second/square meter?
-
To translate viscosity values from Imperial units to non-SI units still used in some engineering contexts, aiding integration of legacy and modern data.
-
Are these units part of the SI system?
-
No, both pound-force second/sq. foot and kilogram-force second/square meter are non-SI units used in specific legacy or regional applications.
Key Terminology
-
Pound-force second per square foot
-
An Imperial/US customary unit of dynamic viscosity quantifying a fluid’s resistance to shear flow, equivalent to one pound-force of shear on one square foot area with a unit velocity gradient.
-
Kilogram-force second per square meter
-
A non-SI dynamic viscosity unit that measures resistance to shear deformation, equal to one kilogram-force second per square meter and related to the pascal-second SI unit.
-
Dynamic (Absolute) Viscosity
-
A measurement of a fluid's resistance to flow or internal friction under applied shear stress.
