Recommended watch order for the Ranma ½ series, based on release order.

MAL is a bit weird about grouping, but in essence there are:
- 161 main series episodes
- 12 episodes of OVAs
- 3 movies
- 7 special episodes, mostly recaps and music videos
- An advertisement for the "It's a Rumic World" exhibition

So in total, that's about 186 episodes worth of Ranma ½ content, plus a short crossover advertisement.

In terms of manga, the original Ranma ½ manga is where all of the adapted anime content comes from. It's hard to give a chapter where the anime "leaves off" because so much was skipped/altered/added for the adaptation - it's generally regarded as best just to start from the beginning. However, if you really want to not repeat any stories, the main series' latest adaptation is chapter 229, and the OVAs' latest adaptation is chapter 365.

There's also Eiga + OVA Ranma ½, a manga adaptation of the Michi wo Tsugu Mono OVAs and the Chou Musabetsu Kessen! Ranma Team vs. Densetsu no Houou movie released after the fact. It's made by directly using animation cells from the OVAs and movie, so you're not missing much by skipping this one. Maybe for the best, as it seems to be fairly obscure.

There was also a live-action adaptation in 2011.
