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 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. Note that "degree Celsius" conforms to this rule because the "d" is lowercase.— Based on The International System of Units, section 5.2.
