Neither of these are necessarily useful on their own, but they can be very useful in tandem with other code.
Some simple examples:
Those examples don't necessarily make sense out of context, unfortunately. The more you know about vector math, the more apparent the utility of these values should be.
Remember that vectors express a direction and length. A unit vector, with length one, can be thought of as expressing a pure direction. That's very useful in game development.
