What Is This Tool?
This converter allows you to transform dynamic viscosity values measured in micropoise [µP], a cgs unit, into millinewton second per square meter (mN·s/m²), which is based on the SI system. It helps users translate very low viscosity measurements to more commonly used units for comparison and analysis.

Use the converter primarily for very low viscosity values where micropoise is practical
-
Cross-check historical micropoise data before comparing with modern SI measurements
-
Ensure measurement instruments are sensitive enough for low-range viscosity readings
-
Understand that unit scale differences may affect measurement interpretation
-
Use the tool for standardizing viscosity data in scientific and engineering workflows
Limitations
-
Micropoise units are suited for very low viscosities and not ideal for higher viscosity fluids
-
Precision may be constrained by differences in unit scales and instrument sensitivity
-
Historical micropoise data require careful validation when compared to millinewton second/sq. meter values
Frequently Asked Questions
-
What does micropoise [µP] measure?
-
Micropoise [µP] is a unit of dynamic viscosity representing fluid internal resistance to shear in cgs units, equal to 1×10⁻⁶ poise or 1×10⁻⁷ pascal-second.
-
Why convert micropoise to millinewton second/sq. meter?
-
Converting micropoise to millinewton second/sq. meter helps translate low-range viscosity measurements into widely used SI units for easier comparison and analysis.
-
Is this conversion suitable for high viscosity fluids?
-
No, micropoise measures extremely low viscosities and may not be practical for fluids with higher viscosity levels.
