How to Convert Pascal-second to Pound per Foot-second
- 1 Pa·s = 0.6719689751 lb/(ft·s)
- 1 lb/(ft·s) = 1.488163944 Pa·s
- Example: convert 15 Pa·s to lb/(ft·s): 15 Pa·s = 15 × 0.6719689751 lb/(ft·s) = 10.07953463 lb/(ft·s)
Formula
lb/(ft·s) = Pa·s × 0.6719689751395
or lb/(ft·s) = Pa·s ÷ 1.48816394357
Derivation from SI units:
- 1 Pa·s = 1 N·s/m² = 1 kg·m⁻¹·s⁻¹
- 1 lb/(ft·s) = 0.45359237 kg ÷ (0.3048 m × 1 s) = 1.4881639436 Pa·s
Both units are defined exactly, so the factor is exact. Pascal-second definition: pascal-second; Pound per Foot-second definition: pound per foot-second.
Worked examples
- A reading of 0.01 Pa·s converts to 0.006719689751 lb/(ft·s).
0.01 Pa·s × 0.6719689751 = 0.006719689751 lb/(ft·s) - A value of 2.5 Pa·s is 1.679922438 lb/(ft·s).
2.5 Pa·s × 0.6719689751 = 1.679922438 lb/(ft·s)

Where it's used
Pascal-seconds are used for engineering fluid-flow and Reynolds-number calculations, while pounds per foot-second appear in heat-transfer and chemical-engineering correlations in US units. Both measure dynamic (absolute) viscosity, so the conversion is a fixed factor.

Frequently asked questions
How many pounds per foot-second are in 1 pascal-second?
1 Pa·s = 0.6719689751 lb/(ft·s).
How do I convert pascal-seconds to pounds per foot-second?
Multiply the value in Pa·s by 0.6719689751, or divide it by 1.488163944. For example, 15 Pa·s × 0.6719689751 = 10.07953463 lb/(ft·s).
Is the Pa·s 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).
