How to Convert Poise to Pound per Foot-second
- 1 P = 0.06719689751 lb/(ft·s)
- 1 lb/(ft·s) = 14.88163944 P
- Example: convert 15 P to lb/(ft·s): 15 P = 15 × 0.06719689751 lb/(ft·s) = 1.007953463 lb/(ft·s)
Formula
lb/(ft·s) = P × 0.06719689751395
or lb/(ft·s) = P ÷ 14.8816394357
Derivation from SI units:
- 1 P = 1 dyn·s/cm² = 0.1 Pa·s
- 1 lb/(ft·s) = 0.45359237 kg ÷ (0.3048 m × 1 s) = 1.4881639436 Pa·s
- 1 P = 0.1 Pa·s ÷ 1.48816394357 Pa·s per lb/(ft·s) = 0.06719689751395 lb/(ft·s)
Both units are defined exactly, so the factor is exact. Poise definition: poise; Pound per Foot-second definition: pound per foot-second.
Worked examples
- A reading of 1 P converts to 0.06719689751 lb/(ft·s).
1 P × 0.06719689751 = 0.06719689751 lb/(ft·s) - A value of 10 P is 0.6719689751 lb/(ft·s).
10 P × 0.06719689751 = 0.6719689751 lb/(ft·s)

Frequently asked questions
How many pounds per foot-second are in 1 poise?
1 P = 0.06719689751 lb/(ft·s).
How do I convert poise to pounds per foot-second?
Multiply the value in P by 0.06719689751, or divide it by 14.88163944. For example, 15 P × 0.06719689751 = 1.007953463 lb/(ft·s).
Is the P to lb/(ft·s) 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).
