Formula
Formula
Pa·s = cP × 0.001
Multiply any value in centipoise by 0.001 to obtain the value in pascal-seconds.
Worked example
Convert 1000 cP to Pa·s.
- 01Start with 1000 cP.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 Pa·s.
Result1000 cP = 1 Pa·s

FAQ
What is the conversion factor from cP to Pa·s?
1 cP equals 0.001 Pa·s. To convert, multiply the value in centipoise by 0.001.
How do I convert 1 cP to Pa·s?
1 cP = 0.001 Pa·s. For any value, multiply by 0.001.
How do I convert Pa·s back to cP?
Divide by the same factor — or equivalently, multiply by 1000. So 1 Pa·s = 1000 cP.
When would I need to convert centipoise to pascal-second?
Dynamic viscosity conversions between cP 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).
