Convert Stokes to Kilostokes
Convert Stokes (St) to Kilostokes (kSt) instantly and accurately.
Conversion Formula
kSt = St × 0.001
About Stokes
The stoke (St) equals 1 cm²/s = 10⁻⁴ m²/s, the CGS unit of kinematic viscosity named after Sir George Gabriel Stokes. Its hundredth part, the centistoke, is now dominant, but the stoke still appears in older fluid-mechanics texts and archival API and ASTM data. Water at 20 °C ≈ 0.01004 St; air at 20 °C ≈ 0.1516 St. 1 St = 100 cSt = 10⁻⁴ m²/s.
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.
