This SI unit is named after Michael Faraday. As with every International System of Units (SI) unit named for a person, the first letter of its symbol is upper case (F). However, when an SI unit is spelled out in English, it is treated as a common noun and should always begin with a lower case letter (farad)—except in a situation where any word in that position would be capitalized, such as at the beginning of a sentence or in material using title case.
