Importance is the quality or state of being important; consequence; significance
It seems like we rank things sometimes on a scale of importance.  For example if I was assigned a big homework assignment then that would be ranked highly important on my, to do list just because it's a big part of my grade and grades are a big part of my life.  In other words grades are of very high importance in my life and the same for many other of my peers.  That's an example of what importance means to me.
