Our Hunspell-derived misspelling index lists 15 documented wrong-spelling variants for Fahrenheit, with forms such as "afhrenheit", "fahernheit", and "fahhrenheit".

Etymologically, the entry records: From German Fahrenheit, named after Prussian scientist Daniel Gabriel Fahrenheit. 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 Fahrenheit, spelled F-A-H-R-E-N-H-E-I-T, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
