Convert Pounds per foot-hour to Millipascal-seconds
Convert Pounds per foot-hour (lb/(ft·h)) to Millipascal-seconds (mPa·s) instantly and accurately.
Conversion Formula
mPa·s = lb/(ft·h) × 0.4133788732
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.
About Millipascal-seconds
The millipascal-second (mPa·s) equals 10⁻³ Pa·s and is numerically identical to the centipoise (cP). It is the standard unit in modern SI-based fluid-property tables. Water at 20 °C is ≈1.002 mPa·s; blood plasma ≈1.2 mPa·s; light mineral oil 20-60 mPa·s. 1 mPa·s = 10⁻³ Pa·s = 1 cP.
