Browser-based and easy to use for researchers and engineers.
Examples
-
Converting 1 mN·s/m² results in 0.00000000000001 TP.
-
Converting 1000 mN·s/m² results in 1e-11 TP.
Common Use Cases
-
Reporting viscosity of low-viscosity fluids like water for laboratory analysis.
-
Comparing lubricant and hydraulic fluid viscosities in engineering tasks.
-
Studying mantle or lithosphere viscosity in geophysical and planetary science.
-
Characterizing highly viscous polymers or glassy materials in materials science.
-
Conducting theoretical rheological assessments that require large viscosity scales.
Tips & Best Practices
-
Ensure precise input values due to large magnitude differences between units.
-
Use terapoise units only for very high viscosity materials to avoid impractical scales.
-
Verify results when converting extremely small values to prevent rounding errors.
-
Apply the converter in relevant scientific or engineering contexts where unit scaling matters.
Limitations
-
Conversion yields extremely small numerical outputs because of the vast unit difference.
-
Careful management of significant figures is needed to maintain accuracy.
-
Terapoise units are not suitable for low-viscosity fluids due to their very large scale.
Frequently Asked Questions
-
What does millinewton second per square meter measure?
-
It measures dynamic (absolute) viscosity, indicating a fluid's resistance to shear flow, commonly used for low-viscosity liquids.
-
When should I use terapoise units?
-
Terapoise is used for representing extremely high viscosity values in fields like geophysics and materials science where large-scale viscosities need to be expressed.
-
Why is the conversion value so small between these units?
-
Because a terapoise is 10¹¹ pascal-seconds, and millinewton second per square meter is 1×10⁻³ pascal-seconds, their difference in scale results in very small conversion numbers.
Key Terminology
-
Millinewton second per square meter (mN·s/m²)
-
A unit of dynamic viscosity equal to 1×10⁻³ pascal-second, measuring a fluid's internal resistance to shear.
-
Terapoise [TP]
-
A very large unit of dynamic viscosity equal to 10¹¹ pascal-seconds, used for expressing extremely high viscosity values.
-
Dynamic viscosity
-
A property of fluids describing their resistance to shear flow, calculated as shear stress divided by shear rate.
