How to Convert Pound-force Second per Square Foot to Centipoise
- 1 lbf·s/ft² = 47880.25898 cP
- 1 cP = 0.00002088543423 lbf·s/ft²
- Example: convert 15 lbf·s/ft² to cP: 15 lbf·s/ft² = 15 × 47880.25898 cP = 718203.8847 cP
Formula
cP = lbf·s/ft² × 47880.25898034
Derivation from SI units:
- 1 lbf·s/ft² = 4.4482216152605 N·s ÷ 0.09290304 m² = 47.880258980 Pa·s
- 1 cP = 0.01 P = 10⁻³ Pa·s
- 1 lbf·s/ft² = 47.88025898034 Pa·s ÷ 0.001 Pa·s per cP = 47880.25898034 cP
Both units are defined exactly, so the factor is exact. Pound-force Second per Square Foot definition: pound-force second per square foot; Centipoise definition: centipoise.
Worked examples
- A reading of 0.0000209 lbf·s/ft² converts to 1.000697413 cP.
0.0000209 lbf·s/ft² × 47880.25898 = 1.000697413 cP - A value of 0.01 lbf·s/ft² is 478.8025898 cP.
0.01 lbf·s/ft² × 47880.25898 = 478.8025898 cP
