An interval variable is a one where the difference between two values is meaningful. The difference between a temperature of 100 degrees and 90 degrees is the same difference as between 90 degrees and 80 degrees. A ratio variable, has all the properties of an interval variable, but also has a clear definition of 0.0.

A variable is something that varies, meaning that it can take on a number of values. ... Interval-level variables are continuous, meaning that each value of the variable is one increment larger than the previous and one smaller than the next value. Age, if measured in years, is a good example; each increment is one year.

I assume you're asking about the difference in meaning rather than in the way these are written down, so here's my take on this. In my opinion, the only difference here is that inequality is a condition on the values involved, while the interval notation is more of a description.
