Conversion Formula
lb/(ft·h) = kPa·s × 2419088.311
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-hour
The pound per foot-hour (lb/(ft·h)) equals 0.45359237 / (0.3048 × 3600) ≈ 4.134×10⁻⁴ Pa·s. It appears in US heat-transfer and mass-transfer textbooks (e.g., McCabe, Smith & Harriott) where viscosity enters the Reynolds number using consistent hour-based units alongside BTU, ft, and lb quantities. Water at 20 °C is ≈2.42 lb/(ft·h). 1 lb/(ft·h) ≈ 4.134×10⁻⁴ Pa·s.
