An Adelaideth is a unit of time measure. It equates to 15 minutes of regular Earth time as defined by the International System of units. An Adelaideth may also be used as a unit of distance (only in Adelaide), since most of Adelaide speed limits are 60km/h, an Adelaideth approximates 15km. History: The phrase was first coined in 2011 by one Geoffrey Aro when, in discussions with Lovey, he realised that most Adelaide locals stick to a 15 km radius of their place of residence. More than two Adelaideths of travel is for special occasions...or wineries. Plural: Adelaideths.
