Advanced Viscosity Calculator
Calculate viscosity at a given temperature, when viscosity is known at two temperatures.
The viscosity of a liquid as a function of temperature can be approximated with the use of the Andrade correlation. Given two known temperature-viscosity points, the viscosity of a liquid can be calculated for a third target temperature. In the case of lubricating oils, oil producers normally publish the viscosity of their products at two different temperatures.
This web page allows the user to enter two temperature-viscosity points, as well as a third target temperature. The viscosity at the target temperature is calculated when you click the 'Calculate' button.
Note that viscosity units are not shown. Typically viscosities are quoted as cSt with Celsius and as SSU with Fahrenheit. This calculator works equally well with either.
This page can be a useful tool for predicting viscosity at a target temperature, but keep in mind that in real world applications a theoretical viscosity value should always be verified with a viscosimeter.
