Formula
Formula
lb/(ft·s) = mPa·s × 0.000671969
Multiply any value in millipascal-seconds by 0.000671969 to obtain the value in pounds per foot-second.
Worked example
Convert 1000 mPa·s to lb/(ft·s).
- 01Start with 1000 mPa·s.
- 02Multiply by the conversion factor: 1000 × 0.000671969 = 0.671969 lb/(ft·s).
Result1000 mPa·s = 0.671969 lb/(ft·s)

FAQ
What is the conversion factor from mPa·s to lb/(ft·s)?
1 mPa·s equals 0.000671969 lb/(ft·s). To convert, multiply the value in millipascal-seconds by 0.000671969.
How do I convert 1 mPa·s to lb/(ft·s)?
1 mPa·s = 0.000671969 lb/(ft·s). For any value, multiply by 0.000671969.
How do I convert lb/(ft·s) back to mPa·s?
Divide by the same factor — or equivalently, multiply by 1488.164. So 1 lb/(ft·s) = 1488.16 mPa·s.
When would I need to convert millipascal-second to pound per foot-second?
Dynamic viscosity conversions between mPa·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).
