One Piece chapter ↔ episode converter
Type a manga chapter, an anime episode, or a One Pace episode. You get the equivalents in the other two, instantly and without a page load. Covers chapters 1–1190 and episodes 1–1174, filler included.
Why the numbers drift apart
There is no fixed ratio between chapters and episodes, which is why simple arithmetic never works. An episode adapts anywhere from one to three chapters, some chapters are split across two episodes, and roughly 100 episodes are filler that adapt no manga at all — the filler list has every one of them. Episode 4 is the clearest example of how messy it gets: it adapts chapters 1 and 8, with nothing in between, and chapter 1 turns up again as a flashback five hundred episodes later.
