Etymologically, the entry records: From being measured in SI metric measurement (2.5 cm), as a value similar to the size of a US/UK Imperial Standard International Inch (2.54 cm), used in some measurements. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is metric inch, spelled M-E-T-R-I-C- -I-N-C-H, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
