Factor1 P = 0.0671969 lb/(ft·s)
Converter
P
Accepts numbers or expressions, e.g. 150 + 14.7
Result
lb/(ft·s)
Rendered to 6 significant figures.
Formula
Formula
lb/(ft·s) = P × 0.0671969
Multiply any value in poise by 0.0671969 to obtain the value in pounds per foot-second.
Worked example
Convert 10 P to lb/(ft·s).
- 01Start with 10 P.
- 02Multiply by the conversion factor: 10 × 0.0671969 = 0.671969 lb/(ft·s).
Result10 P = 0.671969 lb/(ft·s)

FAQ
What is the conversion factor from P to lb/(ft·s)?
1 P equals 0.0671969 lb/(ft·s). To convert, multiply the value in poise by 0.0671969.
How do I convert 1 P to lb/(ft·s)?
1 P = 0.0671969 lb/(ft·s). For any value, multiply by 0.0671969.
How do I convert lb/(ft·s) back to P?
Divide by the same factor — or equivalently, multiply by 14.88164. So 1 lb/(ft·s) = 14.8816 P.
When would I need to convert poise to pound per foot-second?
Dynamic viscosity conversions between P and lb/(ft·s) are common in fluid characterisation, pump and control valve sizing, pipeline pressure-drop calculations, and lubrication engineering. Centipoise (cP) and mPa·s are the most widely used units in process datasheets; Pa·s is required for most simulation tools.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
