Convert Millipoises to Pounds per foot-hour
Convert Millipoises (mP) to Pounds per foot-hour (lb/(ft·h)) instantly and accurately.
Conversion Formula
lb/(ft·h) = mP × 0.2419088311
About Millipoises
The millipoise (mP) equals 10⁻⁴ Pa·s, an intermediate CGS unit between the micropascal-second gas range and the centipoise liquid range. It is occasionally used in older European scientific literature and in the textile industry for sizing-solution viscosity. Air at 20 °C is ≈ 0.185 mP; a 0.5% polymer solution might read 5-20 mP. 1 mP = 10⁻⁴ Pa·s = 0.1 cP.
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.
