Convert Kilostokes to Square millimetres per hour
Convert Kilostokes (kSt) to Square millimetres per hour (mm²/h) instantly and accurately.
Conversion Formula
mm²/h = kSt × 360000000
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 millimetres per hour
The square millimetre per hour (mm²/h) equals 1/(3.6 × 10⁹) m²/s ≈ 2.78 × 10⁻¹⁰ m²/s. It appears in materials science for solid-state diffusion and thin-film growth studies where hourly timescales are more natural than seconds. 1 mm²/h = 1/3600 mm²/s = 1/3600 cSt.
