Etymology: The unit "inch" is a doublet of "ounce", and that surprise comes from its Roman origin. The Latin "uncia" meant one-twelfth of something, whether a Roman pound or a foot, and it descends from the same Proto-Indo-European root meaning "one" that gave Latin "unus." Old English borrowed it as "ynce," which hardened into the Middle English "ynche" and then "inch." The same Latin word also gave us "ounce," which kept the weight sense of the same twelfth-part division. English did not get the word only from Latin. The Middle English form "inch" was borrowed from Scots, which in turn came from Irish. Old Irish "inis" meant "island" and descended from a Proto-Celtic word, so the length unit and the word for an island share a remote ancestor, though the two senses are unrelated in use. Finally, the word has a Cantonese twist. In Cantonese, the character 寸 is read "cyun3" and means "inch", and it shares its pronunciation with 串, meaning "cocky" or "to provoke." This is a semantic loan rather than a shared word, so the Chinese sense of the unit was matched to an existing term rather than borrowed as a sound.
