If you have the viscosity in centiPoise, divide the centiPoise value by the oil's viscosity to get centiStokes. One stokes (St) is equivalent to 1 square centimeter per second (cm/s). This calculator uses centiStokes (cSt), which are equivalent to mm^2/s. Higher quality oils tend to have higher viscosity indices, and while there are ranges in every category, a synthetic oil will tend to have a much higher viscosity index than its conventional counterpart. Ut U100F (1 + 0. Viscosity - Kinematic Kilostoke, Stoke, Centistoke, square Meter/Second, square Centimeter/Second, square Millimeter/Second, square Foot/Second and more. If you know the viscosity of your oil at 40✬ and 100✬ (100✯ and 212✯) you can easily calculate its Viscosity Index. Viscosity - Dynamic Poise, Centipoise, Pound force-Second/square Inch, Poundal-Second/square Foot, Gram/Centimeter-Second, Slug/Foot-Second, Pound/Foot-Second and more. On the attached Krebs Units to Centipoise conversion chart, read vertically from the known Krebs unit to the curve and then horizontally to the left to the Centipoise value. Oil needs to flow when cold, but not get too thin and runny when it's warm. Step 1: Knowing the Krebs value, convert this value to Centipoise viscosity. That is, oil with a high VI will retain their viscosity over a wider temperature range and work as designed in both hot and cold environments.Ī higher VI is important when your machine will experience a big change in operating temperatures. The higher the viscosity index, the lower the change in viscosity. The degree to which the viscosity decreases determines the Viscosity Index (VI).
1 square centimeter/second 0.0001 square meter/second. square meter/hour to square meter/second, square meter/second to square meter/hour. The kinematic viscosity can also be determined by dividing the dynamic viscosity by the fluid density. This value must be converted back to 1.004 x 10-6 m2/s for use in calculations. 1 square meter/hour m2/h 0.0002777778 square meter/second. m2/s 1.0 m2/s 10000 Stokes 1000000 Centistokes Water at a temperature of 20C has a viscosity of 1.004 x 10-6 m2/s This evaluates to 1.004000 Centistokes. The viscosity of an oil decreases as temperature increases. Complete list of viscosity - kinematic units for conversion. Viscosity Index and what you need to know
