Conversion Formula
ft²/min = cSt × 0.000645834625
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 minute
The square foot per minute (ft²/min) equals 0.3048²/60 ≈ 1.548 × 10⁻³ m²/s. It appears in US HVAC, ventilation, and turbine-cooling design where velocities are quoted in ft/min. 1 ft²/min ≈ 1548 cSt.
