So if I were jiggling, I think I could come up with a speed. I’d figure out how far I'm moving, and how long it takes me to move. So I could measure from far left to far right of the jiggle (let’s say 18in.) and then how far to go from far left to far right and return to the original position. If that’s 2 seconds, then that’s 1½ feet per 2 seconds which can be converted to any other speed such as km/hr.

I’m rather jiggly.

The jiggly argument is about not all parts moving at once or in one direction. If you jiggled to the right by taking one 18 inch step to the right, sticking your left arm straight left, waiving your right arm in a complete circle, holding your left foot 3 inches off the ground, and squatting down 10 inches how far have "you" moved?

How does the thermometer get its answer? I’d measure that part.

The answer by the thermometer is the temperature, which is based on more degrees of freedom. You'll have to define some mapping between the other degrees and velocity.
