What is the conversion factor from centipoise to pascal-second?

1 centipoise (cP) = 0.001 pascal-seconds (Pa·s). This is an exact relationship: cP is defined as one-hundredth of a poise, and 1 poise = 0.1 Pa·s, so 1 cP = 0.001 Pa·s.

Is centipoise the same as millipascal-second?

Yes. 1 cP = 1 mPa·s (millipascal-second). Both units refer to the same quantity; the names come from different unit systems (CGS vs. SI).

What is the viscosity of water in Pa·s?

Water at 20°C has a dynamic viscosity of approximately 1.002 cP, which equals about 0.001002 Pa·s. At 25°C it drops to roughly 0.00089 Pa·s.

When should I use Pa·s instead of cP?

Use Pa·s in scientific publications, SI-based engineering calculations, and software that requires SI inputs. Use cP in industrial and laboratory contexts where it remains a common practical unit.

Does this tool handle very small or very large values?

Yes. The converter works for any positive number. For very small values (like gas viscosities in the 0.01–0.1 cP range) or large polymer values (thousands of cP), the result is displayed with enough decimal places for accuracy.
