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 Square feet per hour
The square foot per hour (ft²/h) equals 0.3048²/3600 ≈ 2.581 × 10⁻⁵ m²/s. It is the standard US unit for thermal diffusivity in the BTU-ft-h system, used alongside heat-transfer and mass-transfer calculations. Air at 20 °C ≈ 0.573 ft²/h; water at 20 °C ≈ 0.0096 ft²/h. 1 ft²/h ≈ 25.81 cSt.
