About Poise (P)
The CGS unit of dynamic viscosity, equal to 0.1 Pa·s. Named after French physician Jean Poiseuille, who studied blood flow in the 19th century. Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some glass/polymer manufacturing tables.
About Pascal-second (Pa·s)
The SI unit of dynamic (absolute) viscosity — the ratio of shear stress to velocity gradient in a flowing fluid. Pa·s is the universal unit in fluid mechanics textbooks, CFD simulations, and lubricant engineering. Water at 20°C has a dynamic viscosity of about 0.001 Pa·s; SAE 30 motor oil is about 0.1 Pa·s; honey is around 10 Pa·s. Rheology, tribology, and polymer melt flow all use Pa·s in scientific publications.

Why Convert Poise to Pascal-seconds?
Converting between Poise and Pascal-seconds is a frequent requirement for engineers, scientists, and students working with dynamic viscosity values. Different industries and regions favour different unit systems, so having a dependable conversion tool saves time and prevents errors in technical calculations. Whether you are verifying a specification sheet, cross-checking simulation results, or preparing a report for an international audience, accurate dynamic viscosity conversion is essential.
Frequently Asked Questions
How do I convert Poise to Pascal-seconds?
The CGS unit of dynamic viscosity, equal to 0. To convert Poise to Pascal-seconds, multiply by 0.1. For example, 25 P equals 2.5 Pa·s.
How many Pascal-seconds are in 1 Poise?
There are 0.1 Pascal-seconds in 1 Poise.
How many Poise are in 1 Pascal-second?
There are 10 Poise in 1 Pascal-second.
What is the formula for Poise to Pascal-second conversion?
The formula is: multiply by 0.1. This means 1 P = 0.1 Pa·s.
Is a Poise bigger than a Pascal-second?
Yes. One Poise is larger than one Pascal-second because 1 P equals 0.1 Pa·s, which is less than 1.
When do you need to convert between Poise and Pascal-seconds?
The SI unit of dynamic (absolute) viscosity — the ratio of shear stress to velocity gradient in a flowing fluid. Poise and Pascal-second are both dynamic viscosity units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
