Viscosity
PtoPa·s
Convert poise (P) to pascal-seconds (Pa·s).
Factor1 P = 0.1 Pa·s
Converter
P
Accepts numbers or expressions, e.g. 150 + 14.7
Result
Pa·s
Rendered to 6 significant figures.
Formula
Formula
Pa·s = P × 0.1
Multiply any value in poise by 0.1 to obtain the value in pascal-seconds.
Worked example
Convert 1 P to Pa·s.
- 01Start with 1 P.
- 02Multiply by the conversion factor: 1 × 0.1 = 0.1 Pa·s.
Result1 P = 0.1 Pa·s

FAQ
What is the conversion factor from P to Pa·s?
1 P equals 0.1 Pa·s. To convert, multiply the value in poise by 0.1.
How do I convert 1 P to Pa·s?
1 P = 0.1 Pa·s. For any value, multiply by 0.1.
How do I convert Pa·s back to P?
Divide by the same factor — or equivalently, multiply by 10. So 1 Pa·s = 10 P.
When would I need to convert poise to pascal-second?
Dynamic viscosity conversions between P and Pa·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).
