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