Modules to calculate the Viscosity Index or the oil viscosity at 100°C

  • When we know the viscosity of an oil at 40°C and 100°C we can calculate its viscosity index.
  • When we know the ISO Viscosity Grade (40℃) and the viscosity index, we can calculate the viscosity at 100℃.

In the first module

Insert:

  • The viscosity at 100℃
  • The viscosity at 40℃
Press “Calculate"
To find the Viscosity Index

In the second module

Insert:

  • The viscosity at 40℃
  • The viscosity index
Press “Calculate"
To find the viscosity at 100℃

In the third module

Insert:

  • The viscosity at 100℃
  • The viscosity index
Press “Calculate"
To find the viscosity at 40℃
