Frequently Asked Questions
-
What is the attostokes unit used for?
-
Attostokes measures extremely low kinematic viscosity, often reported in nanotechnology, molecular dynamics, and nanoscale lubrication studies.
-
How is square millimeter per second related to other viscosity units?
-
Square millimeter per second (mm²/s) equals 1×10⁻⁶ m²/s and corresponds numerically to 1 centistoke (cSt), commonly used in engine oil and hydraulic fluid measurements.
-
Why convert attostokes to square millimeter per second?
-
This conversion translates very small molecular or nanoscale viscosity values into units suitable for practical engineering and fluid analysis at larger scales.
