The farad is named after Michael Faraday. As with every SI unit named for a person, its symbol starts with an upper case letter (F), but when written in full, it follows the rules for capitalisation of a common noun; i.e., farad becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case.
