How many 3 32 in an inchon a ruler

I have a rear wheel drive vehicle and I am pretty certain one of the wheel bearings is going bad. Can hear a squeaking noise while driving and the wheel has a slight wobble. Jack the car up into the air and the tire can be pushed back and forth. No good, of course. I assume this means a bad wheel bearing.

This leads me to question, how urgently do I have to get this done? I don’t have a lot of time and have limited access to facilities and tools. From what I understand the wheel won’t fall off on the highway or lock up or anything, as the axle shaft and hub are one piece, but I will probably fuck up my tires and my axle if I drive on it (Would think any kind of back and force motion is gonna put stress on the C clip inside the diff.)
