What Is This Tool?
This online converter transforms kinematic viscosity measurements from microstokes (µSt), a metric micro-scale unit used for very low viscosities, to square inch per second (in²/s), an imperial unit commonly used in engineering and industrial contexts. It simplifies translating microfluidics, gas dynamics, and lubrication data into US customary units for further analysis and reporting.

Frequently Asked Questions
-
What does microstokes measure?
-
Microstokes (µSt) measure kinematic viscosity, representing very low levels of momentum diffusivity in fluids, especially useful in microfluidics and gas dynamics.
-
Why convert microstokes to square inch/second?
-
Converting to square inch/second allows use of imperial-common units in industries such as lubrication engineering and petroleum refining that rely on US customary measurements.
-
Does this conversion consider temperature or pressure?
-
No, the conversion uses standard unit definitions and does not include corrections for temperature or pressure influences on viscosity.
Key Terminology
-
Microstokes (µSt)
-
A unit of kinematic viscosity equal to 10⁻⁶ stokes, used for measuring very low viscosities especially in microfluidics and gas dynamics.
-
Square inch/second (in²/s)
-
An imperial unit of kinematic viscosity describing the fluid’s internal resistance to flow, equal to the movement of one square inch area per second.
-
Kinematic viscosity
-
The ratio of a fluid’s dynamic viscosity to its density, representing momentum diffusivity in fluid flows.
