-
Convert 1 attopoise (aP) directly to 1 × 10⁻¹⁸ dyne second/sq. centimeter.
Common Use Cases
-
Reporting ultra-low viscosity measurements in molecular and nanoscale research.
-
Comparing theoretical or experimental viscosities of ultracold gases.
-
Laboratory rheology studies involving biological fluids or polymer melts.
-
Engineering calculations where cgs unit standardization is required.
Tips & Best Practices
-
Ensure input values represent very small viscosities appropriate for attopoise.
-
Use precision instruments when measuring extremely low viscosities.
-
Double-check converted results due to very small numerical values.
-
Apply conversion for comparative studies between SI and cgs units.
Limitations
-
Attopoise values convert to extremely small numbers in dyne·s/cm², challenging precise measurement.
-
Measurement and conversion precision may be sensitive to experimental errors.
-
Not typically used in common fluid mechanics with larger viscosity scales.
Frequently Asked Questions
-
What is attopoise used for?
-
Attopoise measures very small dynamic viscosities encountered in molecular dynamics, nanofluidics, and atomic-scale transport studies.
-
How is the dyne second per square centimeter related to poise?
-
The dyne second per square centimeter is equivalent to one poise, a standard cgs unit for dynamic viscosity.
-
Why convert from attopoise to dyne second per square centimeter?
-
Conversion allows relating ultra-small viscosity values to the more commonly used cgs system for laboratory and engineering work.
