About Centistokes

The centistoke (cSt) equals 10⁻⁶ m²/s = 1 mm²/s. It is the dominant unit for kinematic viscosity in industry worldwide. ASTM D445, ISO 3104, and ACEA lubricant specifications all use cSt. Water at 20 °C ≈ 1.004 cSt; diesel at 40 °C: 2.0-4.5 cSt; SAE 40 oil at 100 °C: 12.5-16.3 cSt. 1 cSt = 10⁻² St.

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.
