How to Convert Pascal-second to Pound-force Second per Square Foot
- 1 Pa·s = 0.02088543423 lbf·s/ft²
- 1 lbf·s/ft² = 47.88025898 Pa·s
- Example: convert 15 Pa·s to lbf·s/ft²: 15 Pa·s = 15 × 0.02088543423 lbf·s/ft² = 0.3132815135 lbf·s/ft²
Formula
lbf·s/ft² = Pa·s × 0.02088543423315
or lbf·s/ft² = Pa·s ÷ 47.88025898034
Derivation from SI units:
- 1 Pa·s = 1 N·s/m² = 1 kg·m⁻¹·s⁻¹
- 1 lbf·s/ft² = 4.4482216152605 N·s ÷ 0.09290304 m² = 47.880258980 Pa·s
Both units are defined exactly, so the factor is exact. Pascal-second definition: pascal-second; Pound-force Second per Square Foot definition: pound-force second per square foot.
Worked examples
- Water at about 0.001 Pa·s is 0.00002088543423 lbf·s/ft².
0.001 Pa·s × 0.02088543423 = 0.00002088543423 lbf·s/ft² - 1 Pa·s is 0.02088543423 lbf·s/ft².
1 Pa·s × 0.02088543423 = 0.02088543423 lbf·s/ft²
