In this case centipoises x 0.000672 lbm/ft sec. If you have the viscosity in centiPoise, divide the centiPoise value by the oil's viscosity to get centiStokes. AVAILABLE IN: English Approximate Viscosity Conversions Kinematic Viscosity Absolute or Dynamic Viscosity Sometimes absolute viscosity is given in terms of pounds mass. 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. If you know the viscosity of your oil at 40✬ and 100✬ (100✯ and 212✯) you can easily calculate its Viscosity Index. Oil needs to flow when cold, but not get too thin and runny when it's warm. 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. Learn more about it on our Stokes law calculator. Calculate Viscosity Kinematic viscosity (cSt) Dynamic viscosity (cP) Specific gravity (g/cm) Calculate Kinematic viscosity (cSt) 0 Dynamic viscosity (cP) 0. The degree to which the viscosity decreases determines the Viscosity Index (VI). The viscosity of an oil decreases as temperature increases. 1 square centimeter/second 0.0001 square meter/second. square meter/hour to square meter/second, square meter/second to square meter/hour. 1 square meter/hour m2/h 0.0002777778 square meter/second.
