A Standard Galactic Unit of Time, the Malton Unit contains 25 marbecs, each one  of which contains approximately 60 martrons, each one of which contains 60(ish) Ribecs. Simply put, the Malton Unit contains, roughly, the same amount of time that it takes the planet Amercadia to revolve once on its axis… sort of. Standard Galactic Units are loosely based on the New Terran Units that were adopted soon after the expulsion of Amercadia’s Eastern Hemisphere, once the implementation of the Eastern Matrix (see: Only Possible Recourse, Our) had added the extra marbec to the planet’s rotation and increased (almost doubled, in fact) the time it took for the moon to revolve around the planet.
