Dynamic Viscosity Converter
Convert dynamic viscosity among Pa·s, cP, P, and lb/(ft·s) using Pa·s as the reference.
How to use
- Enter dynamic viscosity and select the source/target units among Pa·s, cP, P, and lb/(ft·s).
Capabilities and scope
Compare units for dynamic viscosity, the quantity relating shear stress to velocity gradient, across SI, CGS, and customary notation.
How it works
Pa·s is the reference with 1 cP=0.001 Pa·s, 1 P=0.1 Pa·s, and 1 lb/(ft·s)≈1.48816394 Pa·s.
Example
1000 cP equals 1 Pa·s.
Useful for
- Convert viscosity data between cP and Pa·s
- Translate poise values to SI
- Compare lb/(ft·s) engineering data
Before you use it
- Kinematic viscosity (m²/s or cSt) is a different quantity; density is required to convert between dynamic and kinematic viscosity.
- Real fluid viscosity can depend strongly on temperature.

Frequently asked questions
Are cP and cSt the same kind of viscosity?
No. cP is dynamic viscosity and cSt is kinematic viscosity; fluid density is needed between them.
