SI multiples

SI multiples of farad (F)
Submultiples Multiples
Value SI symbol Name Value SI symbol Name
10−1 F dF decifarad 101 F daF decafarad
10−2 F cF centifarad 102 F hF hectofarad
10−3 F mF millifarad 103 F kF kilofarad
10−6 F µF microfarad 106 F MF megafarad
10−9 F nF nanofarad 109 F GF gigafarad
10−12 F pF picofarad 1012 F TF terafarad
10−15 F fF femtofarad 1015 F PF petafarad
10−18 F aF attofarad 1018 F EF exafarad
10−21 F zF zeptofarad 1021 F ZF zettafarad
10−24 F yF yoctofarad 1024 F YF yottafarad

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.
