This page converts poise into pascal seconds using the factor 0.1, and shows the reverse figure alongside it. Both units measure how much a fluid resists being sheared, which is why one number does the whole job.

The poise is the CGS unit, named after Poiseuille. Ten poise make one pascal second. The pascal second is the SI unit of dynamic viscosity — the resistance a fluid puts up against being sheared.

Centipoise is dynamic viscosity; centistokes are kinematic. Dividing dynamic viscosity by density gives the kinematic figure, so an oil at 250 cP and 0.9 g/cm3 is 278 cSt, not 250. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into pascal seconds, which is usually more useful than the bare number.

pascal seconds = poise × 0.1

How it works, step by step

  1. Enter the value in poise.
  2. It is multiplied by 0.1, the exact factor between the two units.
  3. The answer is shown in pascal seconds, with the reverse conversion beneath it.
  4. Check the reference table if you want a figure of comparable size.

Worked examples

Water at 20 C: 0.01 P in pascal seconds

At 0.01 P (water at 20 c), the same quantity in pascal seconds is 0.01 × 0.1 = 0.001 Pa·s. One poise is 0.1 pascal seconds, so the numbers shrink as expected.

SAE 30 motor oil at 20 C: 2 P in pascal seconds

At 2 P (sae 30 motor oil at 20 c), the same quantity in pascal seconds is 2 × 0.1 = 0.2 Pa·s. One poise is 0.1 pascal seconds, so the numbers shrink as expected.

How to read your score

0–0ZeroZero poise is zero pascal seconds.
0–1Under one unitThe answer is less than one pascal second.
1–1,000Everyday rangeA typical working figure in pascal seconds.
1,000–—Large valueLarge enough that the exact figure below the gauge is easier to read than the gauge itself.

Frequently asked questions

How many pascal seconds are in one poise?

Exactly 0.1. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.

What is the formula to convert poise to pascal seconds?

pascal seconds = poise × 0.1. Reversed, poise = pascal seconds ÷ 0.1, which is the same as multiplying by 10.

Which is the bigger unit, the poise or the pascal second?

The pascal second. One poise is only 0.1 of a pascal second, so it takes 10 poise to make one pascal second.

What does this quantity actually measure?

Both units measure how much a fluid resists being sheared. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.

What is a poise?

The poise is the CGS unit, named after Poiseuille. Ten poise make one pascal second.

What is a pascal second?

The pascal second is the SI unit of dynamic viscosity — the resistance a fluid puts up against being sheared.

Why does my answer differ from another converter?

Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
