"The price was unrealistically low." "The deadline is unrealistically short." When you use it, you are not just measuring something — you are judging it. You are saying: this number, this hope, this picture of the world could not actually happen, and someone has failed to see that. So there is usually a quiet criticism inside it.

It can attach to a verb too ("he plans unrealistically"), but that sounds stiff; the natural home of this word is right before an adjective. It is a long word and a slightly formal one — in everyday speech people are more likely to say "way too high" or "that's never going to happen."
