Convert Microstokes to Kilostokes
Convert Microstokes (µSt) to Kilostokes (kSt) instantly and accurately.
Conversion Formula
kSt = µSt × 1.000000000e-9
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 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.
