What Is This Tool?
This online unit converter translates dynamic viscosity values from pascal seconds (Pa*s), the SI derived unit, into terapoise (TP), a metric multiple of the poise used to measure extremely high viscosities. It supports scientific and industrial uses requiring scaled viscosity units.
How to Use This Tool?
-
Enter the viscosity value in pascal seconds (Pa*s) into the input field.
-
Select 'pascal second [Pa*s]' as the from unit and 'terapoise [TP]' as the to unit.
-
Click the convert button to see the corresponding value in terapoise.
-
Review the output which uses the formula 1 Pa*s = 1e-11 TP.
-
Use results for applications involving large scale viscosity measurements.

-
Expressing extremely high viscosities in geophysics and planetary science such as mantle and lithospheric rheology.
-
Characterizing very viscous glassy or highly cross-linked polymer systems near solidification in materials science.
Tips & Best Practices
-
Ensure the viscosity value entered is in pascal seconds for accurate conversion.
-
Use terapoise units only for extremely large viscosity values due to their very large scale.
-
Refer to conversion examples to understand scale differences when switching between units.
-
Apply this conversion primarily in scientific and large scale rheological analyses.
-
Avoid using terapoise for common fluid viscosity measurements as precision may be limited.
Limitations
-
Terapoise is only suitable for representing extraordinarily high viscosities and is not practical for everyday fluid measurements.
-
Converting small to moderate viscosities into terapoise results in extremely small decimal values reducing meaningful precision.
Frequently Asked Questions
-
What does 1 pascal second equal in terapoise?
-
One pascal second equals 1e-11 terapoise according to the defined conversion rate.
-
In which fields is the pascal second to terapoise conversion commonly used?
-
This conversion is common in geophysics, planetary science, materials science, and rheology research involving extremely high viscosity values.
-
Why is terapoise not practical for everyday fluid viscosity measurements?
-
Because terapoise represents extremely large viscosity values, it results in tiny decimals when converting smaller viscosities, limiting practical precision.
Key Terminology
-
Pascal second [Pa*s]
-
The SI derived unit of dynamic viscosity representing one pascal of shear stress per unit shear rate, equivalent to 1 N·s/m².
-
Terapoise [TP]
-
A metric multiple of the poise equal to 10^12 poise or 10^11 pascal-seconds, used to measure extremely large dynamic viscosities.
