# Calculate the Viscosity Index

Calculate the Actual Oil Viscosity at the Operating Temperature of your Equipment

If we know the viscosity of an oil at two temperatures we can calculate the viscosity at the temperature we need in our operations.

Normally the data sheet gives us the viscosities at 40 °C y 100 °C, but you can insert any two temperatures and viscosities that you have.

Then insert the temperature for which you need the viscosity and press “Calculate”

 Viscosity Calculator at a Specific Temperature (ASTM D341) Type the Viscosities and Temperatures know and the temperature at which you want the viscosity. Temperature Celsius Viscosity cSt Temperature and Viscosity 1 Temperature and Viscosity 2 Temperature Operational °C Viscosity at Operational Temperature cSt
