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.

About Square millimetres per minute

The square millimetre per minute (mm²/min) equals 1/(6 × 10⁷) m²/s ≈ 1.667 × 10⁻⁸ m²/s. It is used in polymer-film formation and printing-ink diffusion studies where minute-scale time resolution is more convenient. 1 mm²/min = 1/60 cSt.
