About Microstokes

The microstoke (µSt) equals 10⁻¹⁰ m²/s, the smallest CGS subdivision of practical interest for kinematic viscosity. It covers extremely rarified or high-temperature gas viscosity and is rarely encountered outside theoretical research. The centistoke is the practical lower bound in most engineering work. 1 µSt = 10⁻⁶ St = 10⁻¹⁰ m²/s.

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.
