What is the poise unit used for?

The poise (P) measures dynamic viscosity and is commonly used in tribology and polymer processing to specify lubricant and fluid flow behavior.

How does the pascal second differ from the poise?

Pascal second (Pa·s) is the SI derived unit of dynamic viscosity measuring internal resistance to shear, whereas poise is a CGS unit equal to 0.1 Pa·s.

Why is converting poise to pascal second important?

Converting to pascal second standardizes viscosity values, facilitating international communication and accurate engineering calculations.
