How do you convert viscosity from centistoke to Stokes? Getting Started Central Standard Time (CST) to Mountain Standard Time (MST) To find the exact cp of your fluid: cp = cSt x (weight per gallon x 0.120). Is centistokes the same as Centipoise?Ĭentipoise = centistokes x specific gravity where specific gravity is assumed to be 0.8 (except for water). Absolute Viscosity is a measure of a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction and of the oil’s film strength to support a load. Kinematic Viscosity (ASTM D445/ISO3105): 1 centi-Stoke (cSt) = 1 mm2/s. That is, at standard pressure and 15 C temperature, the dynamic viscosity of air is roughly 0.000173 poise, and the kinematic viscosity of air is roughly 0.141 stokes. Stokes = A x Poise / (Fluid Density) where A = 1000, if the fluid density is measured in kg per cubic meter. » Centistokes Conversions: cSt↔m2/s 1 m2/s = 1000000 cSt. Calculate SSU viscosity t = / = 138.9 seconds. The formula for the conversion is: Kinematic (cSt) x Density = Dynamic (cP)Įxample: Converting Centistokes to SSU Viscosity Calculate 4ac = 4 × 0.226 × -195 = -176.28. Density actually provides a way to convert between a kinematic and a dynamic viscosity measurement. How do you convert viscosity to dynamic viscosity?Ī basic difference between the dynamic and kinematic viscosity measurements is density. 1 stokes is a kinematic viscosity of a fluid with a density of 1 g/cm³ and a dynamic viscosity of 1 poise. The kinematic viscosity can also be called diffusivity of momentum since it has the same dimensions as the diffusivity of heat and diffusivity of mass concentration.Ī centistokes (cSt) is a decimal fraction of the CGS unit of kinematic viscosity stokes, which is equal to centimeter per second (cm²/s).
