How many poise are in one pascal-second?

Exactly 10 P = 1 Pa·s. This is because 1 Pa·s = 1 kg/(m·s) and 1 P = 0.1 kg/(m·s) in CGS-to-SI conversion.

What is the difference between dynamic and kinematic viscosity?

Dynamic viscosity (Pa·s or poise) measures a fluid's resistance to shear stress. Kinematic viscosity (m²/s or stokes) is dynamic viscosity divided by fluid density, used when gravity drives flow.

Why is poise still used if Pa·s is the SI unit?

Poise (and centipoise, cP) survived in chemistry and food/pharma because many historical datasets, instruments, and standards predate SI adoption. Water's viscosity at 20 °C is conveniently close to 1 cP, making it a handy reference.

What is viscosity of water in Pa·s?

Water at 20 °C has a dynamic viscosity of approximately 0.001 Pa·s (1 mPa·s), which equals 0.01 P (10 cP).

Can I convert centipoise (cP) using this tool?

Divide your cP value by 100 to get poise, then enter that poise value here. Alternatively, 1 cP = 0.001 Pa·s = 1 mPa·s.
