About Kilostokes
The kilostoke (kSt) equals 1000 St = 0.1 m²/s. It is used for extremely viscous materials such as heavy polymer melts and bitumen at low temperatures, where centistoke values would reach into the hundreds of thousands. 1 kSt = 10³ St = 10⁵ cSt = 0.1 m²/s.
About Square feet per hour
The square foot per hour (ft²/h) equals 0.3048²/3600 ≈ 2.581 × 10⁻⁵ m²/s. It is the standard US unit for thermal diffusivity in the BTU-ft-h system, used alongside heat-transfer and mass-transfer calculations. Air at 20 °C ≈ 0.573 ft²/h; water at 20 °C ≈ 0.0096 ft²/h. 1 ft²/h ≈ 25.81 cSt.
