How to Convert Pound per Foot-second to Poise
- 1 lb/(ft·s) = 14.88163944 P
- 1 P = 0.06719689751 lb/(ft·s)
- Example: convert 15 lb/(ft·s) to P: 15 lb/(ft·s) = 15 × 14.88163944 P = 223.2245915 P
Formula
P = lb/(ft·s) × 14.8816394357
Derivation from SI units:
- 1 lb/(ft·s) = 0.45359237 kg ÷ (0.3048 m × 1 s) = 1.4881639436 Pa·s
- 1 P = 1 dyn·s/cm² = 0.1 Pa·s
- 1 lb/(ft·s) = 1.48816394357 Pa·s ÷ 0.1 Pa·s per P = 14.8816394357 P
Both units are defined exactly, so the factor is exact. Pound per Foot-second definition: pound per foot-second; Poise definition: poise.
Worked examples
- A reading of 0.001 lb/(ft·s) converts to 0.01488163944 P.
0.001 lb/(ft·s) × 14.88163944 = 0.01488163944 P - A value of 0.05 lb/(ft·s) is 0.7440819718 P.
0.05 lb/(ft·s) × 14.88163944 = 0.7440819718 P

Frequently asked questions
How many poise are in 1 pound per foot-second?
1 lb/(ft·s) = 14.88163944 P.
How do I convert pounds per foot-second to poise?
Multiply the value in lb/(ft·s) by 14.88163944. For example, 15 lb/(ft·s) × 14.88163944 = 223.2245915 P.
Is the lb/(ft·s) to P conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
