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 inches per minute

The square inch per minute (in²/min) equals 0.0254²/60 ≈ 1.075 × 10⁻⁵ m²/s. It appears in US coating and printing industry references where area coverage rates in in²/min are combined with kinematic flow data. 1 in²/min ≈ 10.75 cSt.
