Convert Centistokes to Kilostokes
Convert Centistokes (cSt) to Kilostokes (kSt) instantly and accurately.
Conversion Formula
kSt = cSt × 1.000000000e-5
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.
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.
