What is a microstokes (µSt)?

A microstoke (µSt) is a unit of kinematic viscosity equal to one-millionth of a stokes, specifically 1 µSt equals 1e-10 square meters per second.

Why convert microstokes to square meter per second?

Converting to square meters per second allows expressing kinematic viscosity in the SI base unit, facilitating standardized scientific calculations and comparisons.

Is the microstokes unit suitable for all viscosity ranges?

No, microstokes are appropriate only for very low kinematic viscosities. Higher viscosities generally require units like stokes or centistokes.
