About Square inches per second

The square inch per second (in²/s) equals 0.0254² = 6.4516 × 10⁻⁴ m²/s. It is the coherent FPS kinematic unit based on the inch, found in US fluid power, hydraulics, and bearing-design references. 1 in²/s = 645.16 cSt = 6.4516 St.

About Millistokes

The millistoke (mSt) equals 10⁻⁷ m²/s. It appears in research on low-viscosity solvents, dilute polymer solutions, and light gases whose kinematic viscosity is in the sub-centistoke range. 1 mSt = 10⁻³ St = 0.1 cSt = 10⁻⁷ m²/s.
