Use this conversion in contexts where small-scale kinematic viscosity values are relevant, such as microfluidics or aerospace.
Limitations
-
Measurement accuracy may be restricted by the sensitivity of instruments when dealing with very small picostokes values.
-
Pico-scale conversions require careful handling to prevent precision loss in calculations.
-
Square centimeter per second units may be unsuitable for expressing extremely large or very small viscosities without scientific notation.
