Temperature vs Viscosity chart

I would like to know temperature vs Viscosity chart. Here in our region atm temperature varies from 15°C to 45°C. please provide us the comparison chart.

I would obtain some motor oil, place it in a fridge. when cooled take its temp and viscosity. Repeat as oil warms up(or is physically heated). This way you would make your own chart.

The original post does not specify what the material is--oil,water, paint or how he proposes to use that information IE: how is he going to verify the dilutions or ?

Conversion from one viscosity scale to another is essentially independent of the identity of the liquid.

But the effect of temperature on viscosity is extremely dependent on the identity of the liquid. Two different liquids with the same viscosity as each other at one particular temperature, may well have viscosities that are different from each other at some other temperature.

The thing to do is simply apply the principle that Terry suggests, except that you must use whatever is the particular liquid whose temperature-dependence you wish to know.

Dear James,
Sorry for writing a great deal slower than you can read - maybe it's due to the fact that I write much faster than I am able to think.
