About Square foot per second (ft²/s)
An imperial unit of kinematic viscosity equal to ≈ 0.092903 m²/s = 92,903 cSt per NIST SP 811. Ft²/s is a very large unit — appropriate for gaseous and highly mobile fluids but unwieldy for common liquids (water at 20 °C is only 1.08 × 10⁻⁵ ft²/s, which is essentially zero on a normal scale). Primarily encountered in: pre-1990s US-edition fluid-mechanics textbooks (Streeter, Roberson-Crowe, Olson) where the entire problem set is in lb-ft-s units to keep dimensional analysis clean; older US petroleum engineering pipeline-flow literature; and some US Bureau of Reclamation hydraulics publications. Reference values: air at 60 °F ~1.6 × 10⁻⁴ ft²/s; standard atmospheric air at 32,000 ft (jetliner cruise altitude) ~5.5 × 10⁻⁴ ft²/s. Convert ft²/s to m²/s by multiplying by 0.0929; to cSt by multiplying by 92,903.
About Square meter per second (m²/s)
The SI unit of kinematic viscosity (ISO 80000-4 §4-33) — dynamic viscosity divided by density (ν = μ/ρ), with dimensions of length squared per time. Kinematic viscosity captures how readily a fluid flows under inertial forces relative to viscous resistance, and appears directly in the dimensionless Reynolds number (Re = ρVL/μ = VL/ν) that determines laminar vs turbulent flow regimes. m²/s is the reference unit in fluid-mechanics research, CFD solver inputs (Ansys Fluent, OpenFOAM, COMSOL, ANSYS CFX), and Reynolds-number calculations. Real-world liquid values typically span 10⁻⁶ to 10⁻³ m²/s, so most practical engineering uses mm²/s (= 10⁻⁶ m²/s = 1 cSt). Reference values: air at 20 °C 1.5 × 10⁻⁵ m²/s, water at 20 °C 1.004 × 10⁻⁶ m²/s, SAE 10W-30 motor oil ~70 × 10⁻⁶ m²/s at 100 °C, glycerin 1.18 × 10⁻³ m²/s — six orders of magnitude variation across common fluids.

Understanding Square meters per second
The Square meter per second (symbol: m²/s) is a unit of kinematic viscosity. The SI unit of kinematic viscosity (ISO 80000-4 §4-33) — dynamic viscosity divided by density (ν = μ/ρ), with dimensions of length squared per time. Kinematic viscosity captures how readily a fluid flows under inertial forces relative to viscous resistance, and appears directly in the dimensionless Reynolds number (Re = ρVL/μ = VL/ν) that determines laminar vs turbulent flow regimes. m²/s is the reference unit in fluid-mechanics research, CFD solver inputs (Ansys Fluent, OpenFOAM, COMSOL, ANSYS CFX), and Reynolds-number calculations.
