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.
