Conversion Formula
m²/s = µSt × 1.000000000e-10
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.
About Square metres per second
The square metre per second (m²/s) is the SI coherent unit of kinematic viscosity (ν = μ/ρ). Air at 20 °C ≈ 1.516 × 10⁻⁵ m²/s; water at 20 °C ≈ 1.004 × 10⁻⁶ m²/s; glycerol ≈ 1.19 × 10⁻³ m²/s. It is the standard in CFD codes and SI research literature. 1 m²/s = 10⁴ St = 10⁶ cSt.
