Formula
Formula
N·s/m² = P × 0.1
Multiply any value in poise by 0.1 to obtain the value in newton-seconds per square metre.
Worked example
Convert 100 P to N·s/m².
- 01Start with 100 P.
- 02Multiply by the conversion factor: 100 × 0.1 = 10 N·s/m².
Result100 P = 10 N·s/m²

FAQ
What is the conversion factor from P to N·s/m²?
1 P equals 0.1 N·s/m². To convert, multiply the value in poise by 0.1.
How do I convert 1 P to N·s/m²?
1 P = 0.1 N·s/m². For any value, multiply by 0.1.
How do I convert N·s/m² back to P?
Divide by the same factor — or equivalently, multiply by 10. So 1 N·s/m² = 10 P.
When would I need to convert poise to newton-second per square metre?
Dynamic viscosity conversions between P and N·s/m² 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).
