equivalence

If you were having trouble choosing between chocolate cake and an ice cream sundae because you love both equally, you might say these two treats have an equivalence.

The noun equivalence describes the state of being equal, and it can be used any time things are basically interchangeable. If you came down with a stomach bug and there were three different medicines your doctor could prescribe — any one of them being likely to cure you — they would have an equivalence.
