Convert Microstokes to Centistokes
Convert Microstokes (µSt) to Centistokes (cSt) instantly and accurately.
Conversion Formula
cSt = µSt × 0.0001
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 Centistokes
The centistoke (cSt) equals 10⁻⁶ m²/s = 1 mm²/s. It is the dominant unit for kinematic viscosity in industry worldwide. ASTM D445, ISO 3104, and ACEA lubricant specifications all use cSt. Water at 20 °C ≈ 1.004 cSt; diesel at 40 °C: 2.0-4.5 cSt; SAE 40 oil at 100 °C: 12.5-16.3 cSt. 1 cSt = 10⁻² St.
