Convert Millipascal-seconds to Pound-force seconds per square foot
Convert Millipascal-seconds (mPa·s) to Pound-force seconds per square foot (lbf·s/ft²) instantly and accurately.
Conversion Formula
lbf·s/ft² = mPa·s × 2.088543423e-5
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.
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.
