Conversion Formula
µSt = St × 1000000
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 Microstokes
The microstoke (µSt) equals 10⁻¹⁰ m²/s, the smallest CGS subdivision of practical interest for kinematic viscosity. It covers extremely rarified or high-temperature gas viscosity and is rarely encountered outside theoretical research. The centistoke is the practical lower bound in most engineering work. 1 µSt = 10⁻⁶ St = 10⁻¹⁰ m²/s.
