What Is This Tool?
This converter allows you to transform dynamic viscosity measurements expressed in pound-force second per square inch (lbf·s/in²) into slug per foot per second (slug/(ft·s)). These units are commonly used in Imperial and US customary measurement systems, especially in fields like petroleum engineering, polymer processing, and aerodynamics.
