i was reading '*different types of data*'. i understood the concept of nominal and order based data. But i did not have a clear picture about the **difference between interval vs ratio scaled data**. i know the concept of **true zero** and it is absence in interval while it's present in ratio scale, but still i was not satisfied with the concept/examples of kelvin and celsius temperature.

Please give 2 or 3 examples with the differences . It would be helpful.
