Coherence (units of measurement)

Coherence is a unit of measurement that looks at how well two different things are related. Think of it like a puzzle where the pieces have to fit together perfectly. Coherence measures how well those pieces fit together, or how much they make sense when they're put together. For example, if you had two different pieces of a puzzle and they fit together perfectly, that would have a high coherence. It would be like the pieces were meant to go together and make sense together. If the pieces fit together but not very well, then that would have low coherence.
