Factor1 Pa·s = 0.671969 lb/(ft·s)

Converter

Pa·s

Accepts numbers or expressions, e.g. 150 + 14.7

Result
0.671969lb/(ft·s)

Rendered to 6 significant figures.

Formula

Formula
lb/(ft·s) = Pa·s × 0.671969

Multiply any value in pascal-seconds by 0.671969 to obtain the value in pounds per foot-second.

Worked example

Convert 1 Pa·s to lb/(ft·s).

  1. 01Start with 1 Pa·s.
  2. 02Multiply by the conversion factor: 1 × 0.671969 = 0.671969 lb/(ft·s).
Result1 Pa·s = 0.671969 lb/(ft·s)

FAQ

What is the conversion factor from Pa·s to lb/(ft·s)?
1 Pa·s equals 0.671969 lb/(ft·s). To convert, multiply the value in pascal-seconds by 0.671969.
How do I convert 1 Pa·s to lb/(ft·s)?
1 Pa·s = 0.671969 lb/(ft·s). For any value, multiply by 0.671969.
How do I convert lb/(ft·s) back to Pa·s?
Divide by the same factor — or equivalently, multiply by 1.488164. So 1 lb/(ft·s) = 1.48816 Pa·s.
When would I need to convert pascal-second to pound per foot-second?
Dynamic viscosity conversions between Pa·s 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).
