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.
About Stokes
The stoke (St) equals 1 cm²/s = 10⁻⁴ m²/s, the CGS unit of kinematic viscosity named after Sir George Gabriel Stokes. Its hundredth part, the centistoke, is now dominant, but the stoke still appears in older fluid-mechanics texts and archival API and ASTM data. Water at 20 °C ≈ 0.01004 St; air at 20 °C ≈ 0.1516 St. 1 St = 100 cSt = 10⁻⁴ m²/s.
