i calculate the viscosity of oil by conducting experiment by known viscosity of oil, how can i calculate the corresponding temperature?(without using thermometer,thermocouple and any other temperature measuring device. i want only by means of viscosity).
than you,
You can use Arrhenius equation. http://en.wikipedia.org/wiki/Temperature_dependence_of_liquid_viscosity
For this calculation you need to know (from literature or by measurements)value of activation energy.
You may find the answer in the following link, where relationships between temperatures and viscosities are presented.

You can use following link to find temperature by viscosity data according to oil type:
