![]() The graphic curve will be updated as well. All other values will be re-calculated automatically. Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. ![]() The use of any of the calculators’ results is at the user’s sole risk. The calculator below is for informative purposes only. You can calculate pre-filled values of oil classified by ISO 3448 with grades VG22, VG32, VG46 or VG68 (at viscosity Index = 100) or enter specific values for any other oils. Highly suitable for applications in a broad temperature spectrum. These data is enough to determine kinematic viscosity at any other values of temperature and as well Viscosity Index. Excellent zinc-free detergent hydraulic oil with high viscosity index. ![]() the Viscosity Index (VI) by the formulas specified in ASTM D2270 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ISO 2909 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ГОСТ 25371-2018 (`Нефтепродукты.the kinematic viscosity values, depends from temperature, calculated by the formulas specified in ASTM D341 – (‘Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products’).The interpolation calculator provided below is used to determine: Equations are provided for calculating viscosity index for petroleum products having kinematic viscosities above. ![]()
