Conversion Formula
St = ft²/s × 929.0304
About Square feet per second
The square foot per second (ft²/s) equals 0.3048² = 0.09290304 m²/s. It is the coherent FPS kinematic viscosity unit, used in US aerospace, hydraulic machinery, and civil/coastal engineering. Water at 20 °C ≈ 1.082 × 10⁻⁵ ft²/s; air at 20 °C ≈ 1.632 × 10⁻⁴ ft²/s. 1 ft²/s ≈ 92903 cSt.
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.
