Convert Square feet per second to Square metres per second
Convert Square feet per second (ft²/s) to Square metres per second (m²/s) instantly and accurately.
Conversion Formula
m²/s = ft²/s × 0.09290304
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 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.
