Convert dynamic viscosity accurately between pascal-seconds, millipascal-seconds, micropascal-seconds, centipoise, poise, and engineering pound-based units.
Example: a dynamic viscosity of 850 cP. How many Pa·s is that?
Result0.85 Pa·s 850 cP = 0.85 Pa·s
One-unit equivalent1 cP = 0.001 Pa·s A quick way to understand the relationship between the two units.

How is the conversion calculated?The value is converted to pascal-seconds first, the SI unit of dynamic viscosity, then to the requested unit using fixed factors.

Enter a dynamic-viscosity value, then choose the current and target units.
Example: 850 cP equals exactly 0.85 Pa·s.
The converter uses the pascal-second, the SI unit of dynamic viscosity, as its internal reference.
The relationship 1 cP = 1 mPa·s = 0.001 Pa·s is exact, and 1 P = 0.1 Pa·s exactly.
Pound-based units are derived from the exact international pound, international foot and time definitions, with display rounding only when the decimal expansion does not terminate.
This tool changes units only. A material’s viscosity can vary with temperature, and this converter does not predict that change.
FAQ
How many Pa·s are in 1 cP?
1 centipoise equals exactly 0.001 pascal-second.
Is cP the same as mPa·s?
Yes. 1 cP equals exactly 1 mPa·s, so their numerical values are identical.
How many cP are in 1 poise?
1 poise equals exactly 100 cP and exactly 0.1 Pa·s.
What is the difference between dynamic and kinematic viscosity?
They are different quantities. Dynamic viscosity uses units such as Pa·s and cP, while kinematic viscosity uses units such as m²/s and cSt, so this converter keeps them separate.
Does the converter calculate viscosity changes with temperature?
No. This page only converts an existing viscosity value between units. Temperature dependence varies by material and conditions.
