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 Centistoke (cSt)
A CGS kinematic-viscosity unit equal to exactly 0.01 stoke = 1 mm²/s = 10⁻⁶ m²/s. Centistokes is the traditional and still-dominant working unit in the global lubricant industry, petroleum products, and fuel-oil specifications. Industry standards using cSt directly: ISO 3104 / ASTM D445 (the universal capillary-tube kinematic-viscosity test method — every lubricant data sheet in the world traces back to this test), ISO 8217 (marine fuels — DM and RM grades all spec viscosity in cSt at either 40 °C or 50 °C; e.g., MGO 'Marine Gas Oil' is ≤ 6.0 cSt at 40 °C; HFO 'Heavy Fuel Oil' is up to 700 cSt at 50 °C), ASTM D2270 (Viscosity Index calculation from kinematic viscosity at 40 / 100 °C), SAE J300 (engine-oil grading at 100 °C and CCS-tested low-temp cP), ISO VG industrial-lubricant grading (the VG number = cSt at 40 °C, ±10%).

Understanding Square feet per second
The Square foot per second (symbol: ft²/s) is a unit of kinematic viscosity. 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.
It belongs to the imperial measurement system.

Understanding Centistokes
The Centistoke (symbol: cSt) is a unit of kinematic viscosity. A CGS kinematic-viscosity unit equal to exactly 0.01 stoke = 1 mm²/s = 10⁻⁶ m²/s. Centistokes is the traditional and still-dominant working unit in the global lubricant industry, petroleum products, and fuel-oil specifications.
