Conversion Formula
St = m²/s × 10000
About Square metres per second
The square metre per second (m²/s) is the SI coherent unit of kinematic viscosity (ν = μ/ρ). Air at 20 °C ≈ 1.516 × 10⁻⁵ m²/s; water at 20 °C ≈ 1.004 × 10⁻⁶ m²/s; glycerol ≈ 1.19 × 10⁻³ m²/s. It is the standard in CFD codes and SI research literature. 1 m²/s = 10⁴ St = 10⁶ 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.
