Convert Millipoises to Pound-force seconds per square foot
Convert Millipoises (mP) to Pound-force seconds per square foot (lbf·s/ft²) instantly and accurately.
Conversion Formula
lbf·s/ft² = mP × 2.088543423e-6
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 Pound-force seconds per square foot
The pound-force second per square foot (lbf·s/ft²) equals (9.80665 × 0.45359237) / 0.3048² ≈ 47.880 Pa·s, numerically identical to slug/(ft·s). It appears in US civil and structural engineering fluid mechanics, pump hydraulics texts, and older API pipeline standards. A key identity: 1 lbf·s/ft² = 1 slug/(ft·s) ≈ 47.880 Pa·s = 478.8 P.
