Conversion Formula
ft²/min = St × 0.0645834625
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 feet per minute
The square foot per minute (ft²/min) equals 0.3048²/60 ≈ 1.548 × 10⁻³ m²/s. It appears in US HVAC, ventilation, and turbine-cooling design where velocities are quoted in ft/min. 1 ft²/min ≈ 1548 cSt.
