Conversion Formula
lb/(ft·s) = kPa·s × 671.9689751
About Kilopascal-seconds
The kilopascal-second (kPa·s) equals 1 000 Pa·s, used for highly viscous materials such as bitumen binders, polymer melts, and pitch at processing temperatures. Bitumen (road asphalt) at 60 °C has a dynamic viscosity of 100-10 000 Pa·s = 0.1-10 kPa·s; hot-melt adhesives at application temperature are 10-100 kPa·s. 1 kPa·s = 1 000 Pa·s = 10 000 P.
About Pounds per foot-second
The pound per foot-second (lb/(ft·s)) equals 0.45359237/0.3048 ≈ 1.4882 Pa·s, the absolute viscosity unit in the foot-pound-second (FPS) system. It appears in legacy US chemical engineering textbooks and fluid mechanics problems stated in USC units. A heavy fuel oil at 50 °C with viscosity 0.050 Pa·s = 0.0336 lb/(ft·s). 1 lb/(ft·s) ≈ 1.4882 Pa·s = 14.882 P.
