How to Convert Pascal-seconds to Poise

Formula

To convert Pascal-seconds (Pa·s) to Poise (P): multiply by 10

Step-by-Step

  1. Start with your value in Pascal-seconds (Pa·s).
  2. Multiply by 10 to perform the conversion.
  3. The result is your value expressed in Poise (P).

Conversion Factor

1 Pa·s = 10 P

Reverse Factor

1 P = 0.1 Pa·s

Worked Example

Convert 25 Pascal-seconds to Poise: 25 Pa·s = 250 P

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.

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 Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some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.

Why Convert Pascal-seconds to Poise?

Converting between Pascal-seconds and Poise 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 Pascal-seconds to Poise?

The SI unit of dynamic (absolute) viscosity — the ratio of shear stress to velocity gradient in a flowing fluid. To convert Pascal-seconds to Poise, multiply by 10. For example, 25 Pa·s equals 250 P.

How many Poise are in 1 Pascal-second?

There are 10 Poise in 1 Pascal-second.

How many Pascal-seconds are in 1 Poise?

There are 0.1 Pascal-seconds in 1 Poise.

What is the formula for Pascal-second to Poise conversion?

The formula is: multiply by 10. This means 1 Pa·s = 10 P.

Is a Pascal-second bigger than a Poise?

No. One Pascal-second is smaller than one Poise because 1 Pa·s equals 10 P, which is greater than 1.

When do you need to convert between Pascal-seconds and Poise?

The CGS unit of dynamic viscosity, equal to 0. Pascal-second and Poise 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.
