The size of an inductance is expressed in Henrys (after Joseph Henry, an American contemporary of Faraday). A large choke may have an inductance of 10H or more, whilst that of a small coil may be 100μH or even less. A piece of wire has an inductance of about 25nH per inch (or 1μH/m). There''s a more exact formula here .
