How to Convert Pound-force Second per Square Foot to Pascal-second
- 1 lbf·s/ft² = 47.88025898 Pa·s
- 1 Pa·s = 0.02088543423 lbf·s/ft²
- Example: convert 15 lbf·s/ft² to Pa·s: 15 lbf·s/ft² = 15 × 47.88025898 Pa·s = 718.2038847 Pa·s
Formula
Pa·s = lbf·s/ft² × 47.88025898034
Derivation from SI units:
- 1 lbf·s/ft² = 4.4482216152605 N·s ÷ 0.09290304 m² = 47.880258980 Pa·s
- 1 Pa·s = 1 N·s/m² = 1 kg·m⁻¹·s⁻¹
Both units are defined exactly, so the factor is exact. Pound-force Second per Square Foot definition: pound-force second per square foot; Pascal-second definition: pascal-second.
Worked examples
- Water at 68 °F, about 0.0000209 lbf·s/ft², is 0.001000697413 Pa·s.
0.0000209 lbf·s/ft² × 47.88025898 = 0.001000697413 Pa·s - 0.001 lbf·s/ft² is 0.04788025898 Pa·s.
0.001 lbf·s/ft² × 47.88025898 = 0.04788025898 Pa·s
